Question

a tunning fork has a frequency of 256hz .it produce a sound wave of wavelength of 1.3m . what is velocity of sound in air

​

Answer 1

Answer:

velocity = frequency * wavelength

v = 256 *1.3

v 332.8m/s

Answer 2

$\huge \fcolorbox{red}{pink}{Solution :)}$

Given ,

Frequency = 256 Hz

Wavelength = 1.3 m

We know that ,

$\large \sf \fbox{FREQUENCY = \frac{SPEED \: OF \: SOUND}{WAVELENGTH} }$

Substitute the known values , we get

Speed of sound = 256 × 1.3

Speed of sound = 332.8 m/s

Hence , the speed of sound in air is 332.8 m/s
