Vedclass · Answer

(C) The relationship between the speed of sound $(v)$, frequency $(
u)$, and wavelength $(\lambda)$ is given by the formula: $v = 
u \lambda$.$(i)$ Given: $v = 340 \, m \, s^{-1}$, $
u = 256 \, Hz$.Using $v = 
u \lambda$, we get $340 = 256 	imes \lambda$.$\lambda = \frac{340}{256} = 1.328 \, m \approx 1.33 \, m$.$(ii)$ Given: $v = 340 \, m \, s^{-1}$, $\lambda = 0.85 \, m$.Using $v = 
u \lambda$, we get $340 = 
u 	imes 0.85$.$
u = \frac{340}{0.85} = 400 \, Hz$.

Establish the relationship between the speed of sound, its wavelength, and frequency. If the velocity of sound in air is $340 \, m \, s^{-1}$, calculate:
$(i)$ The wavelength when the frequency is $256 \, Hz$.
$(ii)$ The frequency when the wavelength is $0.85 \, m$.
