16.3 Understanding Sound Waves Check

A measure of how long the wave is, taken from one wave to the same point on the

next wave.

If a sound traveling through a medium has a frequency of 520 Hz and a wavelength of 6.92 m, what is

its speed? (If needed, round to the nearest whole number)

What is the wavelength of a 320 Hz sound traveling 330 m/s? (Round to the nearest hundredth (X.XX))

Which wave would travel the fastest in a vacuum, light, or sound?

• Sound Waves would travel the fastest, because light waves are mechanical waves and cannot travel in a vacuum.

• Sound Waves because they are electromagnetic waves and can move in a vacuum.

• Light Waves because they are mechanical waves and mechanical waves can travel in a vacuum

• Light Waves since they are electromagnetic waves, with can travel in a vacuum. Sound waves are mechanical waves and cannot travel in a vacuum.

Would sound waves travel faster in an oven or a freezer?

• Oven because the particles of air are moving faster, which would allow the sound waves to travel more easily.

• Freezer because the particles of air are colder and moving faster, which would allow the sound waves to travel more easily.

• Oven because the particles of air are moving slower, which would allow the sound waves to travel more easily.

• Freezer because the particles of air are colder and moving faster, which would allow the sound waves to travel more easily.
