One way to break down the electromagnetic (EM) spectrum from low frequency (long wavelength, lower energy) to high frequency (short wavelength, higher energy), is to break it up into radio waves, which include "regular" radio waves and microwaves, light, which includes infrared (IR), visible light, and ultraviolet (UV) light, X-rays, and cosmic rays. The radio waves are those we are familiar with. Radio, TV and such. Microwaves are just high frequency radio waves used in radar, communications and the ubiquitous microwave oven. We know light, too. We see it, and we know about the lower frequency light below the visible spectrum which we call infrared. IR is used in the transfer of heat and in many of our remote controls for TV's and such. Visible light is just that, and ultraviolet is the UV we put on sun block to avoid. Insects use UV to "see" things differently. X-rays are high energy EM rays that penetrate us, and we use them for medical and other types of imaging as well as investigation (spectroscopy). Cosmic rays are the highest energy EM waves generated when some nuclear reactions occur and EM energy is released from the nucleus of an atom. You need a link to the Wikipedia article, and you got it.

There are four major types of force called as universal or fundamental forces of nature. They are: 1. Gravitational Force 2. Electromagnetic Force 3. Strong Nuclear Force 4. Weak Nuclear Force
This is essentially correct. As we currently understand it, there are four basic forces in the universe. These are gravity, the strong and weak nuclear forces (strong and weak nuclear interactions), and the electromagnetic force. An electromagnetic wave is an expression of the electromagnetic force, and it is pure energy. There is no matter associated with electromagnetic waves. It might (or might not) be helpful to note that electromagnetic energy can be converted into matter, and we see this happen in an event we call pair production. A link is provided below to a related question for the curious investigator to use.

The Balmer series is a set of spectral lines in the visible region of the electromagnetic spectrum of hydrogen. It consists of four lines in the visible light spectrum resulting from transitions in hydrogen's electron shell to the second energy level. The Balmer series is significant in understanding atomic structure and spectroscopy.
There are four chambers of the heart and two major regions (the base and the apex).
There are four major land regions in Colorado that include the Rocky Mountains and the Great Plains. The other two land regions are the Intermountain Basin and the Colorado Plateau.
