From the items on that list, infrared light has the lowest frequency,
and X-rays have the highest.
infrared light:)
Radio waves have the lowest frequency in all of the electromagnetic spectrum. The next higher frequency energy is microwave, visible light including ultraviolet, infrared, X-ray, then gamma ray
X-rays have the highest frequency in the electromagnetic spectrum.
From lowest frequency to highest, the electromagnetic spectrum consists of radio waves, microwaves, infrared waves, visible light, ultraviolet rays, X-rays, and gamma rays. Heat, or thermal radiation, is also a type of electromagnetic wave, but is not limited to any particular frequency range. Televisions and cell phones use electromagnetic waves in the radio-wave region.
The color spectrum in order of increasing frequency (that also means decreasing band width) is red, orange, yellow, green, blue, violet. So red is the lowest visible frequency. Below that is called infrared and the color with a frequency greater than violet is called ultraviolet. Neither infrared nor ultraviolet is visible to the human eye although there may be other animals that are able to detect them.

X-rays have the highest frequency in the electromagnetic spectrum.
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.
In the visible-light portion of the electromagnetic spectrum, frequencies are lowest near red light (approaching infrared waves) and highest near violet light (approaching ultraviolet rays).

The lowest frequency is effectively zero and this would be in the extremely low frequency (ELF) band in the sub-radio range of the electromagnetic spectrum.
Electromagnetic radiation is characterised by its frequency. Frequency is measured in Hertz, abbreviated Hz. To a radio man 'high frequency' is in the range 2MHz to 30 MHz. Other e-m radiation is listed below, lowest frequency first VHF UHF Microwaves Millimeter waves Infrared Visible Light Ultraviolet Soft X-rays Hard X-rays Gamma rays.
