Answer:
The law of reflection states that if the angle of incidence is 9 degrees, the angle of reflection is 9 degrees.
Step by step explanation:
The angle of incidence
Definition: The angle between the incident ray and the normal is called angle of incidence.
The angle of reflection
Definition : The angle between the reflected ray and the normal is called angle of reflection.
The angle of incidence and angle of reflection are equal. Here angle of incidence = 9° therefore angle of reflection = 9°
