The distance between two successive crests of a wave is 15cm and the velocity 300ms-1. Calculate the frequency.

  • 2.0x102Hz
  • 4.5x103Hz
  • 2.0x103Hz checkmark
  • 4.5x102Hz

The correct answer is: C

Explanation

Wavelength = 15cm = 0.15m

Velocity = 300m/s

V = fx

F = V/Wavelength

F = 300/0.15 Hertz

F = 2 x 103Hz

There is an explanation video available .
