Question

The velocity of sound is $330\text{m/s}$ and the time period of the sound wave is $0.1\text{s}$. Calculate the wavelength of the sound wave.

• A. $33\text{m}$
• B. $330\text{m}$
• C. $3\text{m}$
• D. $0.3\text{m}$

Answer 1

The correct option is A $33\text{m}$

Given, velocity of sound, $\text{v}=330\text{m/s}$
Time period of soundwave, $\text{T}=0.1\text{s}$

The wavelength of the soundwave, $\lambda =\text{v}\times \text{T}$
$\lambda =330\times 0.1=33\text{m}$

Therefore, the wavelength of the sound wave is $33\text{m}$.
