Waves and EMS Test THE RIGHT QUIZ REVIEW STUDY GUIDE

Refraction occurs when a wave changes its                         as it passes through a different medium.

• intensity

• 
  color 

• 
  speed

• frequency

Houses with carpet are much quieter than houses with tile or hardwood floors because of sound wave

• absorption

•  refraction

• reflection

• diffraction

Which is an example of a compressional wave?      

• gamma ray

• X-ray

• sound wave

• water wave

Increasing the amplitude of a sound wave will make it                                          .

• produce beats

• louder

• travel faster

• have a higher pitch

Ocean waves crash on the beach at a velocity of 3.5 m/s.  If the distance between the crests of each wave is 4 m, find the frequency of the waves.

• 0.88 Hz

• 14.0 Hz

• 1.14 Hz

• 
  0.0088 Hz

The picture shows which wave behavior?

• refraction

• reflection

• diffraction

• absorption

An echo is an example of sound wave

• diffraction

• absorption

• reflection

• refraction

What is the velocity of a wave having a frequency of 25 Hz and a wavelength of 10 m?

• 250 m/s

• 35 m/s

• 2.5 m/s

• 0.4 m/s

A glass prism is able to bend light because    

• energy is diffracted when it encounters an obstacles

• the prism creates destructive interference

• light is refracted as it enters a different medium

• the glass and the light’s wavelength create resonance

In 1 second, 4 crests of a wave pass a certain point.  What is the wave’s frequency?

• 4 Hz

• 4 m/s

• 0.25 Hz

• 0.25 m/s
