lyudmila [28]

Answer:

The wavelength is 0.14 m

Explanation:

Given that,

Frequency = 2450 Hz

Speed of sound = 343 m/s

We need to calculate the wavelength

Using formula of wavelength

$v= f\lambda$

Where, v = speed of sound

f = frequency

Put the value into the formula

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

$\lambda=\dfrac{343}{2450}$

$\lambda=0.14\ m$

Hence, The wavelength is 0.14 m
