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

$\huge\mathfrak\colorbox{lime}{{\color{black}{answer~↓~↓~}}}$

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.

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.

According to the law of reflection, images are reflected from a smooth surface, such as a mirror, at the same angle (θ2) as the incidence angle (θ1)
