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
