A ray of light strikes a smooth surface and is reflected. The angle of incidence is 35°.
A
Rays will bounce in all directions, so the angle of reflection will be random.B
Rays will bounce in all directions, so the angle of reflection will be less than 35°.C
Rays will follow the law of reflection, so the angle of reflection will be 35°.D
Rays will follow the law of reflection, so the angle of reflection will be random.9
