Question

A tuning fork having frequency 256hz emits a wave of wavelength 1.35m find the speed of sound in air

Answer 1

Answer:

357.75 m/sec

Explanation:

We should know a Physics formula that is given below:-

Velocity=Wavelength x Frequency

Here,

W=1.35 m

F=256 Hz

V=1.35 x 256

V=357.75 m/sec

Answer 2

The speed of sound in air is 345.6 m/s

Explanation:

Given that,

Frequency of the tuning fork, f = 256 Hz

Wavelength of the tuning fork, $\lambda=1.35\ m$

We need to find the speed of sound in air. The speed of sound is given by the product of frequency and wavelength.

$v=f\lambda$

$v=256\times 1.35$

v = 345.6 m/s

So, the speed of sound in air is 345.6 m/s. Hence, this is the required solution.
