Question

A sound wave has a frequency of 250 Hz and a wavelength of 1.3 m. Calculate the speed of this waves.

Answer 1

325 m/s

Step-by-step explanation:

Frequency of the wave = 250 Hz

wavelength of the wave = 1.3 m

From the wave formula;

v = λf

v = wave speed

λ = wavelength

f= frequency

v = 250 * 1.3 = 325 m/s
