The reason you can’t hear sound while in a vacuum

It needs a medium

The speed of sound will change if you change its:

MediumA.Medium

B.Amplitude

C.Loudness

When I crank up the volume on my radio I’m not only changing how loud my radio is, I’m also changing a sound wave’s

Amplitude

The units of frequency

Hertz (Hz)

Like vibrating wine glasses, an object that is vibrating at its natural frequency is experiencing:

Rock idol Mr. Marrero plays a low pitch note on a guitar followed by a high pitch note.

What property of waves is he changing?

Frequency

Which property of waves are you experiencing when a someone drives by you in a car with a song that has a very low bass that makes your chest vibrate at its natural frequency

Resonance

The type of wave done by fans on a sports event.

Transverse wave

The units in which wavelength is measured
