Question

A sound wave traveling at a speed of 1000 m/s has a frequency of 1 kHz. Its wavelength is ___ m.

hintHint:

  • v=fλ
  • v= wave speed, f= frequency, λ= wavelength 

The correct answer is: 1


    • Wave speed= frequency × wavelength.
    • Given that speed = 1000m/s and frequency= 1Khz =1000Hz.
    • Therefore, wavelength= wave speed/frequency
    = 1000/1000 =1m.
