Question

Humpback whales are known to produce a collection of elaborate

and repeating sounds with frequencies ranging from 20 Hz to 10 kHz. The sound
waves travel through water at speeds of approximately 1400 m/s. Determine the
wavelengths of the waves at the lower and the upper end of this frequency
range.​

Answer 1

70 m.

Step-by-step explanation:

Given,

Frequency, f = 20 HZ

speed of sound, v = 1400 m/s

wavelength of the waves = ?

we know,

v = f λ

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