Question

Establish the relationship between speed of sound, its wavelenth and frequency. If velocity of sound in air is `340 m//s`, calculate :
(i) wavelength when frequency is `256 Hz`.
(ii) frequency when wavelength is `0.85 m`.

Answer 1

N/A
(i) As `v = v lamda = (v)/(v) = (340 m//s)/(256 Hz) = 1.33 m`.
(ii) As `v = v lamda =, v = (v)/(lamda) = (340 m//s)/(0.85 m) = 400 Hz`.
