When one part of the sound wave pushes air particles together, they form a:

• sound wave

• diffraction

• compression

• rarefaction

When one part of the sound wave causes air particles to spread out, they form:

• surface waves

• sound waves

• rarefactions

• compressions

Sound waves can travel through (select all that apply):

• solids

• liquids

• gas

• nothing

When you whisper, you produce sound waves with:

• higher frequencies and lower pitches

• lower frequencies and lower pitches

• lower frequencies and higher pitches

• Nothing! You can't whisper!

Loudness is measured in:

• meters (m)

• Volume (v)

• Decibels (dB)

• Hertz (Hz)

An observer is in front of a firetruck. These waves will have:

• longer wavelengths

• Different properties

• a higher pitch than the waves behind the truck

• the same amplitude as the waves behind the truck

What is density?

• The amount of weight there is in a given amount of space or volume.

• The amount of volume there is in a given amount of weight.

• The amount of space there is in a given amount of volume.

• The amount of matter or mass there is in a given amount of space or volume.
