Question

A
B
Angle of Incidence, angle of Reflection and angle of Deviation.
From the diagram, find
a) angle of reflection
b) glancing angle of incidence
c) glancing angle of reflection
d) angle of deviation
e) sum of the angles of incident, reflection and glancing.
​

Answer 1

Answer:

Glancing angle of incidence is defined as the angle between the incident ray and the reflecting surface.

Hence, angle of incidence + glancing angle of incidence = 90

0

So, angle of incidence =90

0

− glancing angle of incidence =90

0

−30
