sound waves

Multiple Choice

A Sound wave is a ________ because it has to travel through a medium. (Review medium

• Matter wave

• light wave

• mechanical wave

• Electromagnetic waves

Multiple Choice

A Sound wave is also a __________because matter in the medium moves forward and backward along the same direction that the wave travels

• Compressional wave

• Transverse wave

• Longitudinal wave

• microwave

Multiple Choice

What is the under line section of the wave representing?

• compression

• wavelength

• rarefaction

Multiple Choice

What is the under line section of the wave representing?

• compression

• wavelength

• rarefaction

Multiple Choice

What is the under line section of the wave representing?

• compression

• wavelength

• rarefaction

Multiple Choice

Rarefaction is :

• an area when the waves are all pressed together

• an area of low density, not very many of them

• the waves are upside down.

Multiple Choice

Compression is:

• when the waves are all pushed together is a tight area.

• When the waves are in an area of low density.

• the waves are upside down.

Multiple Choice

Rarefaction is the opposite of compression

• True

• false

Multiple Choice

Loudness is the human perception of how much energy a sound wave carries

• true

• False

Multiple Choice

The lower the amplitude of a wave, the more energy it carries.

• true

• false

Multiple Choice

Larger amplitude = louder sound

• True

• False

Multiple Choice

Smaller amplitude = softer sound

• true

• false

Multiple Choice

The_______of a sound is how high or low it sounds

• rarefaction

• Frequency

• Pitch

• compression

Multiple Choice

The ________ of a sound wave is the number of compressions that pass by a given point in one second.

• pitch

• rarefaction

• compression

• frequency

Multiple Choice

The higher the pitch, the lower the frequency.

• true

• false

Multiple Choice

An object that vibrates faster forms a sound wave with a higher frequency.

• True

• False

Multiple Choice

Long wavelength mean...

• everything is even

• higher frequency, higher sounds, more waves

• low frequency, low sound, fewer waves.

• high sound, low freguency, even waves.

Multiple Choice

The energy carried in a sound wave can be described in _________

• waves

• decibels

• hertz

• dollars and cents

Multiple Choice

Sound waves with a higher pitch have a shorter wavelength

• True

• False
