Question

What is the wave velocity if the wave length is 100 cm and the frequency is 2 Hz?

Answer 1

The answer is in attached photo.

Answer 2

Given,

The wavelength is = 100 centimetres

The frequency is = 2 Hz

To find,

The wave velocity of the given wave.

Solution,

The wavelength is = 100 centimetres = 1 metre (SI unit)

We can easily solve this mathematical problem by using the following mathematical formula.

Wave velocity

= Wave length × Frequency

= 1 × 2 (By putting the values.)

= 2 m/s

(The m/s is also the SI unit of the wave velocity.)

Hence, the wave velocity is 2 m/s.
