What is wave frequency?

• Wave frequency is the speed at which a wave travels through a medium.

• Wave frequency is the distance between two consecutive wave crests.

• Wave frequency is the amplitude of a wave.

• Wave frequency is the number of complete waves that pass a given point in a certain amount of time.

What is wave amplitude?

• Maximum displacement or distance from the equilibrium position

• The number of waves passing a point in a given time interval.

• The speed at which a wave travels through a medium.

• The time it takes for one complete wave cycle.

How is wave speed related to wavelength and frequency?

• Wave speed is inversely proportional to wavelength and frequency.

• Wave speed is only related to wavelength, not frequency.

• Wave speed is unrelated to wavelength and frequency.

• Wave speed is directly proportional to wavelength and frequency.
