A ray of light strikes a smooth surface and is reflected. The angle of incidence is 35 degrees What can be predicted about the angle of reflection?

A
Rays will follow the law of reflection, so the angle of reflection will be 35 degrees .
B
Rays will bounce in all directions, so the angle of reflection will be less than 35 degrees .
C
Rays will follow the law of reflection, so the angle of reflection will be random.
D
Rays will bounce in all directions, so the angle of reflection will be random.
