Question

9. State laws of reflection of light with suitable digram
​

Answer 1

Answer:

I = Incident ray

R = Reflected ray

N = Normal  

∠ i = angle of incidence  

∠ r = angle of reflection

There are two basic laws of reflection of light -

(i) The incident ray the reflected ray and the normal to the reflecting

   the surface at the point of incidence lie in the same plane ;

(ii) The angle of incidence is always equal to the angle of reflection i.e

     ∠ i = ∠r
