A period is the time it takes for a wave to travel through one wavelength. And the right answer is B.

What is period?

A period is a time taken for a wave to complete one oscillation.

The S.I unit of period is seconds.

The formula period is given as

Formula:

  • T = v/λ.

Where:

  • T = Period
  • v = velocity
  • λ = Wavelength.

From the formula,  A period can also be defined as the time it takes for one complete wavelength to pass a fixed point.

Hence, A period is the time it takes for a wave to travel through one wavelength. And right answer is B.
