Question ⤵️

Write the velocity of sound when an object has a frequency of 250 Hz and wavelength of 2m ?

Answer ⤵️

As per the given data, we have

λ=100cm=1metre

n=250Hz

Number of waves produced=N=100

Distance travelled=s=?

We know that s=speed×time=v×t and v=λ×n

The time taken to produce one wave is known as Time Period T

It is given by T=

n

1

t=T×N

s=v×t=λ×n×t=λ×n×T×N

=λ×n×

n

1

×N=λ×N

=1×100=100metres

Answer=100metres

Hope it helps you.......
