Question

C. It is a point on the principal axis at which the rays parallel to the principal axis meet or
appear to meet after reflection. For a concave mirror, it lies in front of the mirror and for
a convex mirror, it lies behind the mirror.
1. What does it refer to?
2. Will it vary in distance from pole for different mirrors?
3. Draw its formation in both the cases i.e. concave and convex mirror.
4. Define focal plane and aperture of a mirror.
5. Where will the image be formed if any object is placed at this point in front of a concave
mirror?

Answer 1

Answer:

see it

Explanation:

Rays of light parallel to the principal axis of a concave mirror will appear to converge on a point in front of the mirror somewhere between the mirror's pole and its center of curvature. That makes this a converging mirror and the point where the rays converge is called the focal point or focus
