Wave Behaviors 2

Front

What are the four main interactions of waves with materials?

Back

Reflection, absorption, transmission, and refraction.

Front

Why can we see through jellyfish?

Back

Jellyfish are mostly transparent, allowing light to pass through them.

Front

What happens to the frequency of a sound wave if the source is moving closer to an observer?

Back

The frequency increases.

Front

What is the relationship between frequency and pitch in sound waves?

Back

As frequency increases, the pitch of the sound also increases.

Front

What type of object reflects all colors of light?

Back

A white object reflects all colors of light.

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 moving relative to the wave source.

Front

How does the Doppler effect affect the pitch of a sound?

Back

The pitch of a sound increases as the source moves closer and decreases as it moves away.

Front

What is refraction?

Back

Refraction is the bending of waves as they pass from one medium to another due to a change in speed.

Front

What is the difference between reflection and absorption of waves?

Back

Reflection is when waves bounce off a surface, while absorption is when waves are taken in by a material.

Front

What happens to light waves when they pass through a prism?

Back

They refract and disperse into a spectrum of colors.
