Question

What will be the frequency sound having 0.20 cm as its wavelength, when it travels with a speed of 331 m s1?

Answer 1

The frequency of the sound is 165500 Hz

Explanation:

Given that,

Wavelength, $\lambda=0.2\ cm$

Speed of sound, v = 331 m/s

Let f is the frequency of the sound. It can be calculated as :

$v=f\times \lambda$

$f=\dfrac{v}{\lambda}$

$f=\dfrac{331\ m/s}{0.2\times 10^{-2}\ m}$

f = 165500 Hz

So, the frequency of the sound is 165500 Hz. Hence, this is the required solution.

Answer 2

Answer:

THE ANSWER IS "1655 Hz"

Explanation:

Frequency Sound = n

Wavelength (lambda) = 0.20 m

Frequency of Sound,n = V/lambda

n = 331/0.20 = 1655Hz.
