Question

A ray of light strikes a plane mirror at a glancing angle of 50°. Calculate the angle between the incident and reflected rays

Answer 1

Answer:

80 degree

Explanation:

Glancing angle of incidence =50 degree   .

So, angle of incidence i=90 degree − 50 degree =40 degree  

And, angle of reflection, r=40 degree  

Angle between incident and reflected rays =i+r=40 +40   =80
