5. If the angle between the plane mirror and the incident ray is 38.50 degrees. What are the angles of
incidence and reflection?
kindly help me
thank you...

Answer:
The Reflected ray (R)bounces off of the mirror at the same angle the Incident ray (I) comes in.
The Normal (N) is perpendicular (90 degrees) to the surface of the mirror at the point of incidence.
The angle of Incidence θi is the angle formed between the Incident ray (I) and the normal (N).
In your problem, the angle between I and the mirror is 30 degrees, which means that your angle of incidence θi is 60 degrees.
The angle of incidence and the angle of reflection are equal.
θi = θr
60 degrees = θr
Your angle of reflection is 60 degrees
