Question

A wave has a wavelength of 5 mm and a frequency of 2hz. At what speed does the wave travel?

Answer 1

Answer: $0.01m/s$

Explanation:

$v=f$λ

We need our wavelength of 5mm to be in meters.

$5mm(\frac{1m}{1000mm} )=0.005m$

Plug this info into the formula

$v=(2hz)(0.005m)$

$v=0.01m/s$
