Question

A wave with a frequency of 14Hz has a wavelength of 3 meters. At what speed will this wave travel​

Answer 1

42 m/s

Step-by-step explanation:

by definition of the velocity(speed) of a wave,

The velocity of light, v, is the product of its wavelength, λ , and its frequency, f.

V= fλ

frequency - number of occurances in a unit time

(check the graph)

`velocity=frequency*wave.length\\=14Hz*3m\\=42 ms^(-1)`
