What is amplitude as it refers to sound waves?

• The distance between the same two points on a wave

• The number of waves per second

• The measure of the height of the wave

• The frequency of the wave

The distance from any point on a wave to the corresponding point on the next wave.

• Amplitude

• Wavelength

• Frequency

• Compression

The total number of waves produced in one second is called the ________ of the wave.

• Vibration

• Echo

• Frequency

• Amplitude

What is a pitch (as it relates to sound)?

• the intensity of a vibration

• the amplitude of a sound wave

• volume of sound

• highness or lowness of a sound

If you want to change the pitch of a sound, you have to change the ______

• frequency

• amplitude

• height

• volume

Which of these waves would have a higher pitch?

• Low Frequency

• High Frequency

• Frequency does not determine pitch

What happens when you increase the amplitude of a sound?

• It makes the sound travel faster

• It makes the sound louder

• It increases the wavelength of the sound

• It increases the frequency of the sound

True or False: Sound travels better through solids than through liquids

• True

• False

The __________________ the frequency, the ____________________ the pitch and vice versa.

• higher, lower

• lower, higher

• higher, higher

• Frequency does not affect pitch

What is sound?

• A type of energy made by vibrations that moves through a medium such as a gas, liquid or solid

• A wave of electrical and magnetic energy moving together through space

• A type of electromagnetic wave that is visible to the eye

• A very low frequency electromagnetic wave that is used for the transmission of radio and television signals
