Question

The angle between incident ray and reflected ray is 60 degree.what is the value of angle of incidence ?????

Answer 1

Answer:

30° is the angle of incidence

Answer 2

Answer:

angle of incidence=angle of reflection

if angle between incident ray and reflected ray is 60°, then angle of incidence+ angle of reflection=60°

angle of incidence= 60°-angle of reflection

if angle of incidence=angle of reflection

then angle of incidence= 60- angle of incidence

angle of incidence+angle of incidence= 60°

2 angle of incidence= 60°

angle of incidence= 60/2

=30°
