______ refers to the distance that a wave traverses in one second.

Correct option is A

The correct answer is: (a) Wave velocity

• Wave velocity refers to the speed at which a wave propagates through a medium.

• It is the distance traveled by a wave per unit of time, typically measured in meters per second (m/s).

• The formula for wave velocity (v) is given by: $$v = f \times \lambda$$

• where:

  • f is the frequency of the wave (the number of oscillations per second),

  • λ (lambda) is the wavelength (the distance between two consecutive points in phase on a wave, like crest to crest or trough to trough).

Information Booster:

• Wavelength: The distance between two consecutive crests or troughs in a wave.

• Frequency: The number of oscillations or cycles completed by a wave per second.

• Amplitude: The maximum displacement of a point on the wave from its equilibrium position.

• Time Period: The time taken for one complete cycle of the wave to pass a given point.
