Question

5. The angle between Cind) Oncedent say and selected say 90°, then the angle of incidence is_____________________​

Answer 1

Answer:

your ans is 45 degree

Explanation:

The answer to this is really simple….

Since angle of incidence is equal to the angle of reflection, we can also say that angle between the incident ray and reflected ray is twice the angle of reflection or incidence.

Thus, as per above case angle of incidence =(90/2) = 45 degree.
