Question

The angle between the
incident ray and the reflected
ray 70 degree. What is the
measure of incident angle?​

Answer 1

Answer:

Similarly refracted ray is the angle between the refracted ray and normal. As said they are equal. Therefore, Angle of incident = 70/2 = 35 degrees.

Answer 2

given:

    angle between i and r = 70 degree

  the i and r are bisected by normal

so the,

      angel of incidence = 35 degree

mark whatever, you think my answer deserves!
