If 10 waves pass a point every $16s$ what is the frequency of the wave? 

•  $10Hz$  

•  $1.6Hz$  

•  $0.625Hz$  

•  $0.312Hz$  

Which of the following would you hear as a low pitched sound?

• sound wave with a frequency of $50Hz$

• sound wave with frequency of $10,000Hz$

• sound wave with an intensity of $10dB$

• sound wave with an intensity of $100dB$

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

• Increases

• Decreases

• Neither

As a longitudinal wave moves forward, the particles move:

• perpendicular to the wave's motion

• parallel to the wave's motion

• stand in one place

• move completely down the spring
