What is the rate at which a wave moves through water, and is measured in knots?

Show answer & explanation

Correct answer: B

Explanation

The correct asnwer is option 2 i.e. Wave speed.

  • Wave speed is the rate at which the wave moves through the water, and is measured in knots.
  • The velocity of the wave depends on its frequency 'f' and wavelength '. The speed of a wave is an important parameter, as it allows us to calculate how fast a wave spreads in the medium, which is the substance material carries the wave.
  • In ocean waves, it is the water, while in the case of sound waves, it is the air.
