Question

The speed of a sound wave is $330m{s}^{-1}$ and its frequency is $550Hz$. What is its wavelength?

• A. $0.4m$
• B. $4m$
• C. $0.6m$
• D. $6m$

Answer 1

Answer: (C)

$0.6m$

The relation between wavelength $\left(\lambda \right)$, speed of wave$\left(v\right)$, and frequency of wave$\left(f\right)$ is-

$v=f\lambda$

$\lambda =\frac{v}{f}$

$v=330m{s}^{-1}$

$f=550Hz$

$\Rightarrow \lambda =\frac{330}{550}$

$\Rightarrow \lambda =0.6m$
