Question

Light is incident on a flat surface making an angle of 10 with the surface. What is the angle of incidence? What is the angle of reflection?​

Answer 1

Answer:

Explanation:angle of reflection and incidence is 80degree

Answer 2

Answer:

The angle of reflection is 80 degrees.

Solution:

• In the given question we are given the angle between that is incident on the surface and the surface.
• Now since we know the incident angle is always calculated around the perpendicular or normal drawn from the point of incidence.
• Hence angle of incidence would be the difference between the perpendicular and angle between the incident ray and surface.

The given angle with the surface is angle of 10.

So, The incident angle is always calculated perpendicular or normal (90 degrees) to the point of incidence.

then,

                     = 90-10 = 80 degrees.

• Hence we get the value of 80 degree as incident angle after reflection also the angle remains same hence this angle also is 80 degrees.
