Question

If the angle between the mirror and the incident ray is 75°, the angle of reflection is______​

Answer 1

Explanation:

Since the angle between the mirror and the incident ray is 75 degrees, the angle of incidence (i.e., angle between the incident ray and the normal) will be 90–75=15 degrees.

Now, from the laws of reflection, we know that angle of incidence is equal to angle of reflection.

Therefore, angle of reflection is 15 degrees.

Answer 2

Answer:

15 degrees the correct answer.
