Question

A bat emits a pulse of sound of wavelength 0.0085 m. Calculate the frequency of the sound. ​

Answer 1

Answer:

   v = 4.0 10⁴ Hz

Explanation:

The bat emits sound in the air, so we can use the speed of sound in air

          v = 344 m / s

also the expression that relates the wavelength and frequency with the speed of the wave

          v = λ f

          f = v / λ

let's calculate

          v = 344/0.0085

          v = 4.0 10⁴ Hz
