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:
Resonance

A secondary earthquake wave looks like this:
Up and down
In what direction would you move if the wave is moving toward you?
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
Meters (m)
It takes 2 seconds for two cycles to pass through a point. What is the period of this wave?
1 second
How many degrees out of phase are the following waves?
180
How many nodes and antinodes does the following standing wave have?
N = 5
A = 4
An example of Resonance
Wine glass
Etc
The Doppler Effect
An apparent change in frequency in sound emitted by a moving source is known as?
This figure shows the movement of a noisy car and the sound waves it produces, at which point would an observer hear the highest frequency?
A
