Question

What happens to the wavelength as the frequency of a whale noise changes from 200hz to 300hz

Answer 1

Answer:

When there is an increase in the frequency of sound waves, the wavelength decreases.

Explanation:

Given data,

The frequency of the whale changes from 200 Hz to 300 Hz

The formula for frequency and wavelength is,

                             λ = v/f

Where v is the velocity of the sound waves in water (1531 m/s)

The wavelength at 200 Hz is,

                             λ = 1531/200

                                = 7.655 m

The wavelength at 300 Hz is,

                             λ = 1531/300

                                = 5.1 m

Hence, when there is an increase in the frequency of sound waves, the wavelength decreases.
