SPHERICAL MIRRORS (CURVED MIRRORS)

I. CONCAVE MIRRORS

where: C - center of curvature, O - object, F- principal focus, f - focal length, v- vertex

Note: If the incident ray is parallel, reflected ray passes through F. If it passes F, reflected ray is parallel. And if it passes C, the reflected ray is still at C.

Defining an image: Is it real or virtual? Where is it located? Is it reduced or enlarged? Is it inverted or upright?

You can identify whether the image is reduced or larged by simply looking at the ray diagram. In the second picture, you can see that the image formed, labeled 'I', is larger than the object 'O' thus the "enlarged" in the definition.
