A grunting porpoise emits a sound of 61 Hz sound. What is the wavelength of this sound in water, where the speed of sound is 1500 m/s? Answer in units of m

Answer:

Frequency= 61Hz

speed of sound = 1500m/s

wavelength=?

speed = frequency×wavelenth

1500 = 61 #

===> # = 1500/61

# = 24.6 m

Given the frequency and speed of the sound, the wavelength of the sound emitted by the grunting porpoise in water is 24.6m

Wavelength

Wavelength is simply the distance over which the shapes of waves are repeated. It is the spatial period of a periodic wave.

From the relationship between wavelength, frequency and speed relation;

λ = v ÷ f

Where λ is wavelength, v is velocity/speed and f is frequency.

Given the data in the question;

  • Speed of the sound v = 1500m/s
  • Frequency f = 61Hz = 61s⁻¹
  • Wavelength λ = ?

To determine the wavelength of the sound, we substitute our given values into the expression above.

λ = v ÷ f

λ =  1500m/s ÷ 61s⁻¹

λ =  24.6ms/s

λ =  24.6m

Given the frequency and speed of sound, the wavelength of the sound emitted by the grunting porpoise in water is 24.6m.
