Question

A ray of light is incident on the point P. If the incident ray and the reflected ray are at 90˚ to each other, what can you say about the path of the incident ray?

Answer 1

Answer:

What is the angle of incidence of a ray of light if the reflected ray is at an angle of 90° to the incident ray? Answer: the angle of incidence= angle of reflection. According to the question, given I + r= 90 degree I = r hence, I + I =90 degree 2i = 90 degree. I= 45 degree.
