Answer:
In the electromagnetic spectrum, radio waves have the largest wavelength and therefore the lowest frequency.
Explanation:
The wave frequency is related to its wavelength by the next equation:
[tex]f=\frac{c}{\lambda}[/tex]
where [tex]f[/tex] if the frequency, [tex]c[/tex] is the speed of light and [tex]\lambda[/tex] 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 [tex]\lambda[/tex] becomes greater, [tex]f[/tex] must decrease.
And the radio waves are those that have a greater wavelength in the electromagnetic spectrum, therefore they have the lowest frequency.
