Sound is a transverse wave.
What is the relationship between frequency and wavelength?
Frequency and wavelength are directly related.
Wavelength increases as frequency increases.
Frequency has no effect on wavelength.
Frequency and wavelength are inversely related.
What happens to sound waves as they travel through different mediums?
Sound waves travel slower in solids than in liquids.
Sound waves do not travel through any medium.
Sound waves travel faster in solids than in liquids, and faster in liquids than in gases.
Sound waves travel at the same speed in all mediums.
Which of the following is NOT part of the electromagnetic spectrum?
Sound waves
Microwaves
Radio waves
Infrared waves
What is the unit of frequency?
Watts (W)
Joules (J)
Volts (V)
Hertz (Hz)
How does the frequency of a wave affect its pitch?
Higher frequency results in a higher pitch, and lower frequency results in a lower pitch.
Lower frequency results in a higher pitch
Frequency has no effect on pitch
Higher frequency results in a lower pitch
What is the primary medium through which sound travels?
Air
Metal
Wood
Water
What is the wavelength of a wave?
The wavelength of a wave is the total energy carried by the wave.
The wavelength of a wave is the distance between consecutive points of the same phase.
The wavelength of a wave is the amplitude of the wave.
The wavelength of a wave is the speed of the wave divided by its frequency.

What is the difference between transverse and longitudinal waves?
Transverse waves move perpendicular to wave direction; longitudinal waves move parallel.
Transverse waves are sound waves; longitudinal waves are light waves.
Transverse waves move parallel to wave direction; longitudinal waves move perpendicular.

Amplitude
What is the correct formula for wave speed?
Wave speed = frequency x wavelength
Wave speed = amplitude x wavelength
Wave speed = amplitude x period
Wave speed = frequency x period
As wavelength decreases, the crests of the wave:

Speed
Wavelength
As air particles become less crowded a region of lower density and pressure is created. This part of a longitudinal wave is called a:
Crest
Compression
Rarefaction

As air particles are pushed together, they create a region of higher density and pressure in a longitudinal wave. These areas are called:
Trough
Compression
Rarefaction
Frequency
What is the pitch of a sound wave?
How loud or soft sound is.
How high or low sound is.
A material that sound travels through.
Back and forth movement of the air particles.
What is the volume of a sound wave?
How loud or soft sound is.
How high or low sound is.
A material that sound travels through.
Back and forth movement of the air particles.
Why can't we hear sound in space?
The helmet blocks the sound and you can't take it off to hear it.
Sound travels so slow in vacuum, that it never gets to your ears.
Sound needs a material to travel through, so it can't travel through vacuum.
Don't know, I've never been to space.
Why do we hear echos?
Sound waves get reflected off a surface and travel back to us.
There is a second sound source emitting sound back at us.
Sound waves get refracted and bend back to us.
