LIGHT

Light behaves as a particle and a wave. Soundwaves travel through air (medium). Light has no medium (wave property). Photons make up light (particle property)

Energy in each photon is based on frequency.

E = hf, where h is Plank's constant which is approximately equal to 6.626 x 10^-34 J.S

Blue light bends most while red light bends the least.

CORPUSCULAR THEORY OF LIGHT (1704)

• Isaac Newton
• Contains a stream of small particles
• Travels in straight lines at great speeds
• reflected from mirrors in a predictable way

WAVE THEORY OF LIGHT

• Thomas Young
• Light is a wave
• undergoes diffraction and interference (Young's double-slit experiment)

LIGHT AS PARTICLE

• position "x", momentum p=mv, mass "m"

LIGHT AS WAVE

• wavelength, amplitude, frequency

WAVES vs PARTICLES

• a particle is localized in space and has discrete physical properties such as mass.
• Wave is inherently spread out, could have amplitudes in a continuous range
• waves superpose and pass through each other, while particles collide and bounce off each other.

Diffraction

 -spreading out of the plane waves as they pass through a hole.

Interference

1. Constructive Interference - occurs where wave crests meet
2. Destructive Interference - occurs where wave crest and trough meet.

BLACKBODY RADIATION

• Blackbody is an object which totally absorbs all radiation that falls on it
• Any hot body radiates light over the whole spectrum of frequencies

PHYSICS

This week, we had a series of test for evaluation of what we learned throughout the past  months. We were given series of problems that we have to solve dealing with index refractions, mirrors, mirror equations, lens, lens equations even the compound lenses.

We also had a chapter test which pretty much summarizes everything we discussed.

We also had this new agreement that in every chapter test, one should get at least 75 percent of the number of items correct or else they will have remedial classes.

However, remedial classes aren't that bad, are they? :)

IMAGE FORMATION FOR CONVERGING LENSES

IMAGES FORMED IN DIVERGING LENSES

RESEARCH

This week, we were taught on how to do the Chapter 2 or the Review of Related Literature.

According to our teacher, he told us that there should be three things your RRL should have: First, it should have informations from any published literature on the topic i.e. encyclopedia, etc. Second, it must have a supporting research problem in which is related to your problem. And third, it should contain your own statement saying how important are these related studies and literature are to your study.

Currently, we are finding a related and relative research study about our project. And I hope we can find one soon.

LENS

Lens are two reflective surfaces joined together. There are two types of lenses: diverging lens and converging lens.

3 Types of Converging Lenses and Diverging Lenses

Converging lenses collects light and lets them converge in one point.

Diverging lenses scatters light, thus the word.

Note: If the distance of the object is infinite, the image formed is a point.

Equation:

Sign conventions:

Note: Converging Lens are positive lens whereas diverging lens are negative lens.

INTRODUCTION

1.1BACKGROUND OF THE STUDY

                Cleanliness has been one of mankind’s biggest concerns in his abide. It is undeniable that cleanliness has been playing a crucial role in terms of health, comfort and virtue on man for the past millennia. However, keeping this hasn’t also been easy.

                Focusing on the most basic place in the community, -our homes –people often find household cleaning as a tiring job. There’s this feather dusting, arranging of furniture, sweeping and mopping the floors. In cleaning the floor, the all-time favorite vacuum cleaner came to solve the hardships o this task. But considering the fact that these floors are usually kept shiny and dust-free, mopping the floor is no exemption.

                This is undeniable that people are getting busier every now and then. The pile of schedules and work steal most of their times and energy. Because of this, keeping the household clean has been quite difficult to maintain compare to the situation decades ago.

                Currently, a new device has been released in the market called Sugoi Remote Control Mop by Kyosho Egg. This is a remote control mop that allows you to operate it and mop the floors without doing many efforts. Just sit on the couch and let it clean using the remote control. This innovation has been really handy for people doing the household chores. But, some flaws were observe in this device.

                First, the Sugoi Mop is quite expensive amounting to almost $40 or approximately Php 1,812. Not all people can afford this convenient mop. Considering this case, not everyone can also benefit in the comfort this mop brings.

                Second, the mop can only clean dusts from the floors and some consumers in online markets complained that it was just like a toy and not really for cleaning. Though it can make the floor shiny, this is not enough to polish quite dirty floors. This is because, the cloth used in this mop has no force to push it down the floor hence not much force is used to polish the floor. The less force is used, the less shiny and less clean.

                Although there are also existing robomops or automatic robot mops which are better than the RC floor mops, they also come with high prices making them unaffordable for people of average income.

                On the other hand, an article in an innovation website cited that there is an alternative for this remote controlled toy vehicle.

1.2 STATEMENT OF THE PROBLEM

                The main objective of this study is to produce an improvised mop which is more efficient in cleaning and is more affordable compared to the ones released in the market using materials that are easily found in malls and department stores.

                Specifically, the following sub-problems are aimed to be answer:

1.       How efficient is your improvised floor mop?

2.       What is the significant difference in the output in cleaning between the RC floor mop and the improvised one?

3.       Is there a difference in terms of effort exerted and output when using the improvised RC floor mop than the human manual mopping?

1.3 HYPOTHESIS

HO1. Radio controlled/ remote controlled cars can be efficient replacements for the body of the remote controlled mop providing that this toy car is also attached with a mop and in order to make the mop exert more effort on the floor, a block of wood or anything that is heavy enough can be used in order to push the mop on the floor.

HO2.  There is no significant difference between improvised RC mop performs similarly to the commercial remote controlled mop and though it provides a lot more comfort compared to human manual mopping, the output in human manual mopping is still better.

1.4SIGNIFICANCE OF THE STUDY

                The fact that this is remote mop and offers a great comfort and relief to people who are tired enough to clean their floor is one of its greatest asset when talking about the significance. This study allow this mop to be more affordable and more efficient in cleaning by correcting the obvious flaws such as its expensive price and the remarkably little force it exerts upon the floor resulting in it not really suitable for general cleaning.

                Generally, once this study is pursued, this will boost the mop’s potential to a higher percent and improve the quality of living on citizens around the globe particularly those who can’t afford to clean their houses anymore due to their lack of strength and endurance, at the same time make the price more affordable.

                Particularly, the housewives or those people who don’t hire helpers in their house, this innovation can lighter their loads thus, giving them more time for themselves and to do their unfinished business instead of spending the whole day, cleaning and working their bodies off.

                This study will also benefit the janitors, janitress and the workers in establishments and households as this will make their works easier and lighter at the same time, enlighten them from burdens.

                To the researchers themselves as this study will improve their creativity, hardworking attitudes, patience and develop their characters which will strengthen their foundations in the future.

                This study will also be of benefit to the market since this study will hopefully come out with an improvised, cheaper yet more efficient RC floor mop which will attract a lot of practical buyers and add on their source of income.

                This will also benefit other researchers and innovators. This study gives them additional knowledge in remote control devices opening the door of new opportunities and innovations that will benefit mankind in the future.

1.5 SCOPE AND LIMITATIONS OF THE STUDY

                This study attempts to create an improvised RC floor mop based on the models released on the market lately. The study will be conducted within the city’s vicinity chosen by the researchers and the basis for the general acceptability will be only the cleaning time and efficiency in comparison to the human manual mopping.

                This study is limited to creating only a more efficient and more affordable floor mop. The qualities of the improvised device will only be compared to the RC mops in the market. This will not include the robot mops. This study is also focused on creating an improvised RC mop that will almost equal the outputs of human manual mopping. Nevertheless, it’s not really attempting to create a device better than the traditional way of mopping.

1.6 DEFINITION OF TERMS

Mop – the improvised remote control mop

Traditional way – old way of mopping (human manual mopping)

Regular – RC Mop in the market

We already submitted this to our teacher in Research subject and he said he will return it to us soon. I know this will have corrections and revisions and I'm excited about those :)
