Question

A wave is moving in air with a velocity of 340m/s .Calculate the wavelength if its frequency is 512vibrations /sec

Answer 1

wavelength=velocity/ frequency
=340/512
=0.664 m

wavelength=66.4 cm

Answer 2

Answer:

The wavelength of the wave is 0.664m.

Explanation:

The relation between wavelength, velocity, and frequency of the wave is calculated as,

$f=\frac{v}{\lambda}$        (1)

Where,

f=frequency of the wave

v=velocity of the wave with which it is moving

λ=wavelength of the wave

From the question we have,

The frequency of the wave(f)=512 vibrations/sec

The velocity of the wave(v)=340m/s

By placing the value of frequency and velocity in equation (1) we get;

$512=\frac{340}{\lambda}$

$\lambda=\frac{340}{512}$

$\lambda=0.664m$

Hence, the wavelength of the wave is 0.664m.
