Two plane mirrors are inclined to each other at an angle 60°. If a ray of light incident on the first mirror is parallel to the second mirror, it is reflected from the second mirror
Options:
Answer:
B
Solution:
Two reflections turn the ray by .
Take the ray initially along the second mirror (direction 0°).
Final direction is 240°, the same line as 60°.
The first mirror makes 60° with the second mirror, so the ray is parallel to the first mirror.
