How to find angle between two inclined plane mirrors?

Click For Summary
SUMMARY

The angle between two inclined plane mirrors can be determined using the formula for angle of deviation, which is defined as the difference between the initial ray and the final ray. When a ray of light is incident on the first mirror parallel to the second mirror, the angle of deviation is calculated as (360 - 2#), where # represents the angle of inclination between the mirrors. In this discussion, the angle of inclination is specified as 60 degrees, leading to an angle of deviation of 240 degrees.

Two plane mirrors are inclined to each other at an angle. If a ray of light incident on the first mirror is parallel to second mirror, is reflected from the second mirror parallel to the first mirror then what is the angle between the two mirrors.
please help me solve it.

Use the formula:- angle of deviation between initial ray and final ray=(360-2#) where # is the angle of inclination between two mirrors. First find out angle of deviation then put the value in the formula.

Here angle of deviation is (180+#) and angle of inclination is 60.
