WAVE INTERACTIONS

Front

What is the Law of Reflection?

Back

The Law of Reflection states that when a wave (like light) strikes a reflective surface, the angle of incidence is equal to the angle of reflection.

What is diffraction?

Back

Diffraction is the bending of waves around obstacles or through openings, causing the waves to spread out.

Can only light waves be reflected?

Back

False. Other types of waves, such as sound waves and water waves, can also be reflected.

What is reflection in wave interactions?

Back

Reflection occurs when a wave bounces back after hitting a barrier, maintaining its energy and direction.

What happens to a wave when it enters a new medium?

Back

When a wave enters a new medium, it changes speed, which can cause it to bend.

What is refraction?

Back

Refraction is the change in direction of a wave as it passes from one medium to another due to a change in speed.

What is the angle of incidence?

Back

The angle of incidence is the angle between the incoming wave and the normal (a line perpendicular to the surface at the point of incidence).

What is the angle of reflection?

Back

The angle of reflection is the angle between the reflected wave and the normal at the point of reflection.

What is absorption in wave interactions?

Back

Absorption occurs when a wave's energy is taken in by the medium it travels through, reducing the wave's intensity.

What is interference in wave interactions?

Back

Interference is the phenomenon that occurs when two or more waves overlap, resulting in a new wave pattern.
