Question

What is the velocity of a wave with a frequency of 760 Hz and a wavelength of 0.45 m?

Answer 1

`342\ \text{m/s}`

Explanation:

In general , the velocity `v` of wave having frequency `f` & wavelength `\lamda` is given as

`v=f\lambda`

Hence, the velocity `v` of wave having frequency `f=760\ Hz` & wavelength `\lamda=0.45\ m` is given as

`v=760\times 0.45`

`=342\ \text{m/s}`
