Question

angle of incidence 15 degree into angle of reflection​

Answer 1

Answer:

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.
