8.2 Sound Unit Lesson 14 - OpenSciEd

Front

What happens to the frequency of a wave when its amplitude increases?

Back

The frequency stays the same.

Front

True or False: Sound travels fastest through gases (air).

Back

False.

Front

What is the part of a longitudinal wave where the particles of the medium are close together called?

Back

Compression.

Front

What is reasoning in the context of an argument?

Front

What is the difference between compression and rarefaction in a longitudinal wave?

Back

Compression is where particles are close together, while rarefaction is where particles are spread apart.

Front

What is sound?

Back

Sound is a type of energy made by vibrations that travels through a medium such as air, water, or solids.

Front

How does temperature affect the speed of sound?

Back

Sound travels faster in warmer temperatures because the particles in the medium move more quickly.

Front

What is the medium in the context of sound waves?

Back

The medium is the substance through which sound waves travel, such as air, water, or solids.
