Wave Behaviors 2

Front

What is the Doppler effect?

Back

The Doppler effect is the change in frequency or wavelength of a wave in relation to an observer who is moving relative to the wave source.

Front

What happens to the pitch of a sound when the source is moving closer to you?

Back

The pitch of the sound increases.

Front

What is reflection in wave behavior?

Back

Reflection is when a wave bounces off a surface and changes direction.

Front

What is refraction?

Back

Refraction is the bending of waves as they pass from one medium to another, changing their speed.

Front

What is diffraction?

Back

Diffraction is the spreading out of waves when they pass through a narrow opening or around obstacles.

Front

What is constructive interference?

Back

Constructive interference occurs when two waves meet and combine to make a wave with a larger amplitude.

Front

What is destructive interference?

Back

Destructive interference occurs when two waves meet and combine to make a wave with a smaller amplitude.

Front

How do light waves behave when they pass from air to water?

Back

Light waves bend as they pass from air to water due to a change in speed.

Front

What is the relationship between frequency and pitch?

Back

Higher frequency results in a higher pitch, while lower frequency results in a lower pitch.

Front

What is wave speed?

Back

Wave speed is the distance a wave travels per unit of time.
