Facts about Frequency.

Choose the correct statements.

• The SI unit for frequency is hertz (Hz)

• Frequency is related to how rapidly the object producing the wave vibrates,

• The frequency of the wave is the same as the number of vibrations the object makes per second.

• All of the above.

Select the statement which is false.

• The longer the wavelength the lower the frequency. The shorter the wavelength the higher the frequency.

• Divide the number of wavelengths by time to calculate and find the frequency of waves.

• A higher frequency produces a lower pitch.

• The unit decibel (dB) describes the intensity and the loudness of sound.
