Consider a spherical mirror of radius of curvature 14 cm and arc length 22 cm. (Arc length is the length of the section of the mirror formed by a plane containing principal axis). This mirror may have significant spherical aberration. Which of the following can be a distance from pole at which a ray parallel to principal axis crosses the principal axis after one reflection from the mirror? (Use : )
Options:(select one or more)
Answer:
A, B, C
Solution:
Paraxial focal length .
With significant spherical aberration, marginal rays cross the axis closer to the pole than f.
So the crossing distance can be 5, 6 or 7 cm, but not beyond 7 cm.
Answer: A,B,C
