Wave Behavior & Interference

Front

What is the amplitude of a wave?

Back

The amplitude of a wave is the maximum distance that the wave's particles move from their rest position. It is a measure of the wave's energy.

Front

What happens when two waves meet?

Back

When two waves meet, they can interfere with each other, resulting in constructive or destructive interference.

Front

Define constructive interference.

Back

Constructive interference occurs when two waves meet in phase, resulting in a wave with a larger amplitude.

Front

Define destructive interference.

Back

Destructive interference occurs when two waves meet out of phase, resulting in a wave with a smaller amplitude or cancellation.

Front

What is reflection in wave behavior?

Back

Reflection is the bouncing back of a wave when it hits a barrier or an object.

Front

What is transmission in wave behavior?

Back

Transmission is the passing of a wave through a medium without being absorbed or reflected.

Front

What is absorption in wave behavior?

Back

Absorption is the process by which a wave's energy is taken in by a material, converting it to other forms of energy.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.

Front

How do you calculate the resultant amplitude of two waves in constructive interference?

Back

In constructive interference, the resultant amplitude is the sum of the amplitudes of the two waves.
