List the parts of the electromagnetic spectrum from longest wavelength to shortest wavelength

The rays of the electromagnetic spectrum from shortest to longest wavelength are: radio waves, microwaves, infrared rays, optical rays, ultraviolet rays, X-rays, and gamma-rays.

EDIT: He has these backwards, the shortest wavelength is created by Gamma-Rays and the longest is Radiowaves.

Remember- high energy = short wavelength.

The relationship of both of them
