Establish the relationship between speed of sound, its wavelength and frequency. If velocity of sound in air is 340 ms–1, calculate
(i) wavelength when frequency is 256 Hz.
(ii) frequency when wavelength is 0.85 m.
Ans. Derivation of formula υ = vλ
(i) 340 = 256 λ
λ = 1.33 m
(ii) 340 = v (0.85)
v = 400 Hz
