Question

A wave has a wavelength of 0.02m and period of 8.0*10^-2 seconds. calculate it's speed. (showing working)​

Answer 1

v = 0.25 m/s

Step-by-step explanation:

Given that,

The wavelength of a wave,
`\lambda=0.02\ m`

Time period of the wave,
`T=8* 10^(-2)\ s`

We need to find the speed of a wave. The speed of wave is given by :

`v=(\lambda)/(T)\\\\v=(0.02)/(8* 10^(-2))\\\\v=0.25\ m/s`

So, the speed of the wave is 0.25 m/s.
