Question

What is the frequency of mechanical wave if wavelength is 12.5 m and velocity is 25 m/s

Answer 1

By wave formula,

We know that v=lambda (wavelength)* frequency

Answer 2

The frequency of mechanical wave if wavelength is 12.5 m and velocity is 25 m/s is  2 Hz

1. The relation between the frequency , wavelength and velocity of a mechanical wave is
2. Wavelength = Velocity / Frequency
3. SI unit of Wavelength = meter (m) ,Velocity = meter per second (m/s) and Frequency = Hertz (Hz) or  1/s
4. Given Wavelength = 12.5 m ,Velocity = 25 m/s
5. Frequency = 25 m/s / 12.5 m = 2 Hz
