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

Explanation:

The speed of the wave is,

$v=\frac{\lambda}{T}$

Substituting the values we get,

$\begin{gathered} v=\frac{16}{8} \\ =2\text{ cm/s} \\ =0.02\text{ m/s} \end{gathered}$

Hence, the speed is 0.02 m/s.
