Question

Scientists have detected sound waves with frequencies as low as 13 Hz being produced by

elephants. Assuming a speed of sound of 350 m/s, determine the wavelength of these sound
waves.

Answer 1

The wavelength of the sound waves are, λ = 26.92 m

Step-by-step explanation:

Given data,

The frequency of the sound waves, f = 13 Hz

The speed of sound waves in air, v = 350 m/s

The velocity of the wave in the medium is equal to the product of its wavelength and its frequency.

The formula for the wavelength of the waves is,

λ = v / f

Substituting the given values in the above equations,

λ = 350 m/s / 13 Hz

= 26.92 m

Hence, the wavelength of the sound waves are, λ = 26.92 m
