Sound Waves Exit Ticket

If you want to change the pitch of a sound, you have to change the ___

• frequency
• amplitude
• speed
• volume

This is the unit used to measure the volume of a sound. 

• Decibel
• Medium
• Vibration
• Oscilloscope

This is what you get when sound waves are reflected, or bounce back, off of a hard surface.

• Amplitude
• Pitch
• Volume
• Echo

The speed of a sound wave depends on

• the frequency
• the medium
• both air temperature and medium
• the air temperature

What is a pitch?

• highness or lowness of a sound
• the intensity of a vibration
• the amplitude of the sound wave
• volume of sound

The part of a longitudinal wave where the particles of the medium are close together.

• rarefaction
• compression
• crest
• trough

A disturbance that travels through a medium as a longitudinal wave

• sound
• wavelength
• pitch
• frequency

Material (matter) through which a wave travels

• medium
• Doppler Effect
• sound
• pitch

When a sound is louder what measurement gets bigger?

• Frequency 
• Amplitude 
• Wavelength 
• Crest

What is the Doppler Effect

• Where the wavelength of a wave is shifted due to the source moving

• When a wave is shifted when a body pushes the wave

• Where the apparent wavelength of a wave is shifted due to the source moving
