From longest wavelength to shortest wavelength:

Radio waves

Microwaves

Infrared light

Visible

Ultraviolet

X - rays

Gamma rays

Frequency/energy/wavelength relationship:

As the energy emitted goes up, so does the frequency go up, and the wavelength goes down.

As the energy emitted goes down, so does the frequency go down, and the wavelength goes up.

For colors: longest wavelength to shortest wavelength:
