Question

The speed of wave in a certain medium is 960 m/s. If 3600 waves pass over a certain point of medium in 1 min. The wavelength of wave is

Answer 1

speed of the wave is 960 m per sec
frequency = 3600/60 =60

wavelength = velocity/ frequency
960/60=16

Answer 2

The wavelength of a wave is 16 meters.

Explanation:

The speed of wave in a certain medium is 960 m/s.

Number of waves pass over a certain point of medium in 1 min is 3600.

To find,

The wavelength of a wave.

Solution,

Frequency of a wave is defined as the number of waves passes through a point per second. So,

$f=\dfrac{3600}{60\ s}=60\ Hz$

Let v is the wavelength of a wave. The speed of a wave is given by :

$v=f\lambda$

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

$\lambda=\dfrac{960\ m/s}{60\ Hz}$

$\lambda=16\ m$

So, the wavelength of a wave is 16 meters.
