Question

The frequency wavelength and speed of a sound wave are related as:

• A. $\lambda =vT$
• B. $\lambda =v/T$
• C. $T=v/\lambda$
• D. $\lambda =v^2$

Answer 1

The correct option is A $\lambda =vT$

The frequency $\left(f\right)$, wavelength $\left(\lambda \right)$ and speed $\left(v\right)$ of a sound are related as $v=\lambda f$

Also time period, $T=1/f$ so $v=\lambda /T$ or $\lambda =vT$
