Unit 5 Waves updated 19-20

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

• amplitude

• crest

• trough

• wavelength

What property of the wave is represented by the letter "B"?

• amplitude
• crest
• trough
• wavelength

The number of wavelengths that pass a point each per second is:

• frequency
• period
• longitudinal 
• transverse wave 

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.

What wave has rarefaction and compression?

• longitudinal 
• surface
• heat
• transversal

A wave carries...?

• energy only
• matter only
• the matter carries the energy
• neither

Which wave has a greater frequency?

• A
• B

In a transverse wave, particles move...?

• back and forth
• vertically
• up and down
• wherever the matter's going

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

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

As the ambulance got closer, Mike noticed that the pitch of the siren got higher. This happened because

• diffraction

• refraction

• reflection

• Doppler effect
