Waves

In a longitudinal wave, the particles move...?

• back and forth
• up and down
• vertically
• in the direction of the hertz

What property of this wave is represented by the letter "A"

• amplitude

• crest

• trough

• wavelength

When the frequency of a wave increases, what happens to the wavelength?

• The wavelength is not directly affected by the frequency of a wave.
• The wavelength increases.
• The wavelength decreases.
• More specific information is needed to form a conclusion about the wavelength.

A mechanical wave cannot travel through...

• a vacuum(empty space).
• water.
• air. 
• glass.

Which wave in the diagram has the greatest frequency?

• 1
• 2
• 3
• 4

Which type of wave is pictured here?

• Longitudinal
• Transverse
• Light 
• Electromagnetic

It is the high pressure part of the wave where the particles are close together. It is part A on this picture.

• Compression

• Amplituide

• Rarefaction

• Wavelength

When the sound source moves, the frequency changes
ex. police car siren sounding lower pitch after the car passes

• pitch
• frequency
• Doppler Effect
• medium

A wave has a wavelength of 15m and a frequency of 10Hz. What is the wave speed?

• 1.5 m/s

• 1.5m/s²

• 150 m/s

• 150 m/s²

What is the frequency of a wave equal to?

• 1/Wavelength
• 1/Period
• 1/Velocity
• 1/Amplitude
