Question

According to the law of reflection, _____.

when two waves meet, they reflect
when two waves meet, they interfere
when a wave meets a boundary, the angle of the reflected wave is equal to the angle of the incident wave
when a wave meets a boundary, the angle of the refracted wave will be equal to the angle of the incident wave

Answer 1

its when a wave meets a boundary, the angle of the reflected wave is equal to the angle of the incident wave.

Answer 2

Answer;

When a wave meets a boundary, the angle of the reflected wave is equal to the angle of the incident wave

Step-by-step explanation;

• Reflection is the property of waves in which the waves bounces back upon meeting or hitting the surface of an object or a boundary. It may also refer to the change in the direction of a wave when it meets an interface between two media.

• Therefore, when a wave such as light waves meets an opaque surface, they will bounce back off the surface.
• The reflection of waves obeys the Laws of reflection such that the angle of reflection is equal to the angle of incident wave.
