How to find angle between two inclined plane mirrors?

Click For Summary

Homework Help Overview

The discussion revolves around determining the angle between two inclined plane mirrors based on the behavior of light rays reflecting off them. The original poster presents a scenario where a ray of light is incident on one mirror and reflects off the other, raising questions about the relationship between the angles involved.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the need for a diagram to visualize the problem. The original poster expresses difficulty in resolving the issue despite attempts. A formula related to the angle of deviation and the angle of inclination is mentioned, prompting further inquiry into its application.

Discussion Status

The conversation is ongoing, with participants exploring different aspects of the problem. Some guidance has been offered regarding the formula for angle of deviation, but there is no clear consensus on the solution or approach yet.

Contextual Notes

The original poster has attempted to apply a formula involving angles but indicates uncertainty about its effectiveness. There is mention of a specific angle of inclination (60 degrees) that is under discussion, but the implications of this value are not fully resolved.

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.

Start by drawing a diagram!
 
ya i did but it isn't helping
tried it many a times

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.
