Question

Frequency of 2 hertz and wavelength of 5 meters. Calculate speed.

Answer 1

Speed = 10 m
`s^(-1)`

Step-by-step explanation:

Given

wavelength = 5 m

frequency = 2 Hz = 2
`s^(-1)`

Speed = ?

We know that for all waves, the relationship between wavelength λ, frequency f and speed v is same and given by the equation:

v = fλ

Hence, Speed = 2
`s^(-1)` x 5 m

= 10 m
`s^(-1)`
