Question

in a regular reflection the angle betweeb incident ray and reflected ray is 60 degree. what is value of angle of incidence?​

Answer 1

Angle of incidence is 30°. 30 degrees. This is because "the angle between incident ray and reflected ray" actually means, angle of incidence+angle of reflection. Since angle of incidence=angle of reflection,angle of incidence =(60/2)=39.

Hope it will helps you☺
