Waves

What disturbance sends energy through matter or empty space? 

• a wave
• a trough
• a medium
• a crest

What is the amplitude of a wave related to? 

• volume
• speed
• mass
• height

What is the wavelength of a wave related to? 

• height
• volume
• mass
• distance

What unit is used to describe the frequency of a wave? 

• decibel
• hertz
• meters per second
• wavelength

What happens to a wave when it is refracted? 

• It is bent. 
• It is transmitted. 
• It is reflected.
• It is radiated. 

A wave can make a leaf bob up and down on the water, but it cannot move the leaf toward the shore. This is because waves only transfer 

• matter.
• energy.
• media. 
• crests.

If a wave is traveling at a certain speed and you cut its frequency in half, what would happen to its wavelength? 

• The wavelength would be halved. 
• The wavelength would produce a standing wave. 
• The wavelength would remain the same. 
• The wavelength would be doubled. 

The section of a longitudinal wave where the particles are crowded together is called a 

• rarefaction
• compression
• vibration
• surface wave

The part of a longitudinal wave where the particles are spread apart is called a 

• rarefaction
• compression
• vibration 
• surface wave

For a laboratory experiment, Antonia wants to measure the amplitude of a transverse wave. Which of the following distances is equal to the amplitude of a transverse wave? 

• the distance from one crest to the next
• the distance from the highest point to the lowest point
• the distance from one trough to the next
• the distance from the rest position of the wave to its highest point
