Select the answer(s) that are true about frequency

• frequency is measured in cycles per second, or hertz

• a wave's frequency equals the frequency of the vibrating source producing it

• five cycles per minute is a frequency of five hertz

• any periodic motion has a frequency

Select the answer that tells how wavelength is related to frequency for a wave traveling at a constant speed.

• wavelength is equal to frequency

• wavelength is directly proportional to frequency

• wavelength is inversely proportional to frequency

• a wave with a higher frequency will have a longer wavelength
