Question

Humpback whales are known to produce a collection of elaborate and repeating sounds with frequencies starting at 20 Hz. The sound waves travel through water at speeds of approximately 1400 m/s. Determine the wavelengths of the waves at the for this starting frequency.

70 m.

Explanation:

Given,

Frequency, f = 20 HZ

speed of sound, v = 1400 m/s

wavelength of the waves = ?

we know,

v = f λ

$$\lambda= \dfrac{v}{f}$$

$$\lambda= \dfrac{1400}{20}$$

$$\lambda=70\ m$$

Hence, the wavelength of the wave is equal to 70 m.
