The frequency of a man's voice is 300 Hz. If velocity of sound is 336 m/s, the wavelength of the sound is:

Correct answer: A. 1.12 m

  • A. 1.12 m
  • B. 300 m
  • C. 330 m
  • D. 112 m
  • E. 11201 m

Explanation

We are given thatfrequency=300Hz, and velocity v=336ms−1From the relation v=f×λ,λ=v/f=336/300=1.12mOption "A" is correct.

About Waves

Progressive waves transfer energy through oscillations, with wavelength, frequency, amplitude and wave speed related by v = fλ; sound speed depends on the medium. Superposition produces interference and stationary waves in strings and organ pipes, while simple harmonic motion describes the oscillation itself and must be distinguished from wave propagation.
