Question

How are velocity , frequency and wavelength related to each other ?



Please explain ...

Thanks
:)

Answer 1

Let wave is traveling with speed "v" have frequency "f" and wavelength "λ" .


so relation between them are:-

=). V = f×λ

Answer 2

The distance travelled by the wave in one complete oscillation is called wavelength. It is also defined as the distance between two consecutive particles of the medium, which are in the same phase. It is denoted by λ. Its unit is cm or m.

The velocity of wave is defined as the rate of change of position of wave with respect to the time.

Velocity = Distance / Time

We know that, time taken by a wave to travel a distance equal to one wavelength is time period.

Hence, v = λ / T
∵ 1 / T = n
∴ v = nλ

Hence, the velocity of wave is equal to the product of frequency and wavelength.

Frequency is defined as the number of oscillation/vibration completed by a particle of the medium in one second. It is denoted by ν (pronounced as 'nu'). Its unit is hertz (Hz).
