Firstly, frequency is inverse to wavelength. And Hz is a unit of frequency.
Gamma rays are at the end of the spectrum, having the highest frequency and a very damaging, tiny wavelength.
FM radio, in MHz, has a small frequency on the spectrum but is higher than AM.
Now for visible light, yellow light has a higher frequency than red light.
Putting the frequencies in order, AM, FM, red, yellow, gamma.
But wavelengths are inverse, so it would go:
gamma, yellow, red, FM, AM
