Sound waves travel fastest through
air
steel
water
a vacuum
Which of these waves can NOT travel through the vacuum of space?
microwaves
radio waves
light waves
sound waves
Sound waves are transferred by the compression of particles. The closer the particles are to one another, the faster the energy is transferred. Therefore, sound energy directly depends upon the _________ of the medium.
density
mass
pressure
volume
Houses with carpet are much quieter than houses with tile or hardwood floors because of sound wave
absorbtion
diffraction
reflection
refraction
You attend a football game one day and notice a long time difference between when the other side of the stadium stands up to cheer and when you hear them. This time difference would be lessened if
it were warmer
it were less humid
it were located a high altitude
the fans on the opposite side were louder

amplitude
crest
trough
wavelength
Comparing Wave A (black) to Wave B (green), Wave A has a
high crest

If we compare and contrast electromagnetic waves with sound waves, all BUT one statement is true. That is
sound waves require a medium to travel while electromagnetic waves do not.
electromagnetic waves can travel through the vacuum of space while sound waves cannot.
electromagnetic waves must have a medium in which to travel, but sound waves can travel anywhere.
sound waves must bounce off of matter in order to travel while electromagnetic waves do not require matter to be present.
The distance from location C to location E, ________ to __________, equals one wavelength.
amplitude to amplitude
frequency to frequency
compression to compression
compression to rarefraction
Volume or intensity of a sound wave is measured by the size of the _________ and reported in decibels.
amplitude
frequency
trough
wavelength
Sound waves are mechanical waves in which the particles in the medium vibrate in a direction parallel to the direction of energy transport. Identify another name for this type of wave motion.
transverse waves
electromagnetic waves
pressure waves
longitudinal waves
Compression or sound waves behave a lot like transverse or electromagnetic waves. Compression waves exhibit ALL BUT one of the following behaviors. That is
reflection
rarefraction
transfer energy
travel through a vacuum
In a _____________ wave, vibrations are perpendicular to the direction of the wave motion. In a _____________ wave, vibrations are parallel to the direction of the wave motion.
transverse, standing
standing, transverse
longitudinal, transverse
transverse, longitudinal
Listening to the radio, you can hear two stations at once. Describe this wave interaction.
diffraction
interference
reflection
refraction
As a sound wave travels from liquid water into ice, its wavelength would
decrease due to wave speed decreasing as it passes through the ice.
increase because the wave speed and frequency have increased.
decrease since the frequency is now lower.
increase in order to keep the frequency the same due to the increase in speed
Mechanical (sound) waves are unable to travel through a vacuum, such as through space, but radio waves are transmitted to Earth from satellites. How is this possible?
Radio waves are electromagnetic waves.
Satellites are located within our atmosphere.
Radio waves are very high energy mechanical waves.
Radio waves are changed to gamma rays for transmission.
