Question

A dog whistle is designed to produce a sound with a frequency

beyond that which can be heard by humans (between 20 000 Hz and
27 000 Hz). If a particular whistle produces a sound with a frequency
of 2.5 × 104 Hz, what is the sound’s wavelength? Assume the speed of
sound in air to be 331 m/s.

Answer 1

Step-by-step explanation:

The wavelength of a sound wave can be calculated using the formula:

wavelength = speed of sound / frequency

Given that the frequency of the whistle sound is 2.5 x 10^4 Hz and the speed of sound in air is 331 m/s, we can calculate the wavelength as:

wavelength = 331 m/s / 2.5 x 10^4 Hz

wavelength = 0.01324 meters or 13.24 millimeters

Therefore, the sound wave produced by the dog whistle has a wavelength of 13.24 mm.
