Question

Is sound travel the speed 329 m per second if the wavelength is 1.5 cm what is the frequency of the waves will it?

Answer 1

Frequency formula

f = 1 / T and f = c / λ

we have given;

speed (c) = 329 m/s &

wavelength (λ)= 1.5 cm = 1.5/100 m

therefore; f = c / λ

=> f = 329/ 1.5/100

f = 329*100/1.5

= 21933.33 Hz
