Question

write the two laws of reflection of light​

Answer 1

Answer:

law 1- angle of incidence is always equal to angle of reflection

such that angle of refection is given as 30 degree then angle of reflection will also 30 degree

law 2-the incidence ray ;reflected ray,point of incidence ,point of reflection and the normal lies on the same plane ....

hopes it will help u

Answer 2

There are two law of reflection of light which are applicable both in the reflection of light from the plant mirrors or from spherical mirrors. These are:

1. The angle of incidence is always equal to the angle of reflection. i.e. i = r. It means that during the reflection of light if the angle of incidence is 250 then the angle of reflection will also be 250. And if the angle of incidence is 60 then the angle of reflection will also be 600.

2. The incident ray, the normal at the point of incidence of mirror and the reflected ray, all lie in the same plane.
