Question

What is the speed of a 16 cm wave with a period of 8 seconds?

Answer 1

Given:

The wavelength is,

`\lambda=16\text{ cm}`

The period is,

`T=8\text{ s}`

To find:

The speed of the wave

Step-by-step explanation:

The speed of the wave is,

`v=(\lambda)/(T)`

Substituting the values we get,

`\begin{gathered} v=(16)/(8) \\ =2\text{ cm/s} \\ =0.02\text{ m/s} \end{gathered}`

Hence, the speed is 0.02 m/s.
