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 = 0.25m/s`

Step-by-step explanation:

Given

`\lambda = 0.02m` --- Wavelength

`T = 8.0 * 10^(-2)s` --- Period

Required

Determine the velocity of the wave

This is calculated using:

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

`v = (0.02m)/(8.0*10^(-2)s)`

`v = (0.02m)/(8.0*0.01s)`

`v = (0.02m)/(0.08s)`

`v = 0.25m/s`

Hence, the velocity is 0.25m/s
