Best answer
Correct Answer - Option 3 : v = fλ

The correct answer is v = fλ.

  • The wave velocity and the wavelength are related to the wave's frequency and period by vw=λT or vw=fλ.
    • The time for one complete wave cycle is the period T.
    • The number of waves per unit time is the frequency ƒ.
    • The wave frequency and the period are inversely related to one another.

  • Wavelength is the measure of the length of a complete wave cycle. The velocity of a wave is the distance traveled by a point on the wave.
  • The velocity of light, v, is the product of its wavelength, λ, and its frequency, f.
    • This means that the wavelength is the velocity, v, divided by the frequency, f. 
  • In the electromagnetic spectrum, there are many different types of waves with varying frequencies and wavelengths.
    • They are all related by one important equation: Any electromagnetic wave's frequency multiplied by its wavelength equals the speed of light.
