Question

find out the glancing angle for normal incidene on a plane mirror​

Answer 1

Answer:

The angle of glancing = g  - angle with the line of plane mirror

The angle of incidence = 90° - g

The angle of refraction = 90° - g

The angle of deviation from the direction ABC  towards BD :  2 g

Answer 2

Answer:

The glancing angle for normal incidence is 90°.
