Question

Why do radio waves have the lowest frequency of all the waves on the electromagnetic spectrum?

Answer 1

In the electromagnetic spectrum, radio waves have the largest wavelength and therefore the lowest frequency.

Step-by-step explanation:

The wave frequency is related to its wavelength by the next equation:

`f=(c)/(\lambda)`

where
`f` if the frequency,
`c` is the speed of light and
`\lambda` is the wavelength.

What this equation tells us is that the longer the wavelength is, the lower the frequency will be. Since c is a constant as
`\lambda` becomes greater,
`f` must decrease.

And the radio waves are those that have a greater wavelength in the electromagnetic spectrum, therefore they have the lowest frequency.
