Question

Speed (v), wavelength ($\lambda$) and the frequency (f) of sound are related as

• A. $\lambda =v\times f$
• B. $v=f\lambda$
• C. $f=\lambda \times v$
• D. none

Answer 1

The correct option is B

$v=f\lambda$

1. The frequency (f), wavelength (λ) and speed (v) of a sound are related as v=λf

Hence, option B is correct.
