Question

A ray of light makes an angle of 50 degree with the surface S1 of the glass slab . it's angle of incidence will be ............​

Answer 1

since the angle made is 50 degree.......but...when any ray is incidence on the plain, angle of incidence is equal to angle of reflection ...therefore angle of incidence will be 50 degree

Answer 2

Answer:

Explanation:

Hey there,

Since according to the law, angle of incidence is equal to angel of reflection. therefore A ray of light makes an angle of 50° with the surface S, of

the glass slab. Its angle of incidence will be 50 degree as per the rule.

Angle of incidence is the angle through which a ray of light falls on an object whereas angle of reflect is the angle through which that ray of light reflects from the surface of that same object.

I hope the answer was helpful.

Thanks.
