Calculate the wavelength of a sound wave whose frequency is 220 Hz

Question.
Calculate the wavelength of a sound wave whose frequency is 220 Hz and speed is 440 ms–1 in a given medium.

Solution:

Given, frequency, $v=220 \mathrm{~Hz}$;

speed of sound, $\mathrm{v}=440 \mathrm{~ms}^{-1}$

Speed, $v=v \lambda \quad$ or $\quad \lambda=\frac{v}{v}=\frac{440}{220}=2 \mathrm{~m}$
