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
