Question

if frequency of a tuning fork is 400 hz and speed of sound in air is 340 m ​

Answer 1

Answer:

» We know that ,

$\pink{v = f \:\lambda }$

»Given :

Frequency (f) = 400 hz

Velocity (v) = 340 m/s

» To find :

${Wavelength (\lambda)}$

» Solution -

by putting the values

$\green{340 = 400×\lambda}$

lambda = 340/400

${\blue{\boxed{lambda = 0.85 m }}}$
