It is the different types of waves in light. All waves travel at the same speed which is nearly 300 million m/s.
Anyway:
Radio Waves - longest wavelength, smallest frequency
Microwaves
Infrared
Visible Light
Ultraviolet
X-Ray
Gamma Rays - shortest wavelength, largest frequency
The electromagnetic spectrum is the full range of known electromagnetic radiation, ranging from radio waves to gamma rays. Radio waves are at one end of the spectrum with the longest wavelength and the lowest frequency. Gamma rays at the other end have the shortest wavelength and the highest frequency. (frequency = wave oscillations per second) Most electromagnetic radiation can fall into one of the following categories: Radiowave Microwave Infrared Visible (light) Ultraviolet X-rays Gamma Rays [This list is in increasing order of frequency)
Alpha, Beta, Gamma and cosmic are all examples of radiation.Types of radiation could be:Ionizing radiationElectromagnetic radiationInfra red radiation
Look at the list of electromagnetic radiations; there is a large variety of them, but you'll have to decide for yourself what you consider "medium wavelength".
Visible light, which lets humans and other animals see, is part of the electromagnetic spectrum. RF (radio frequency) waves are part of the electromagnetic spectrum. RF transmissions carry radio and television broadcasts. They have the lowest frequency. Microwaves are part of the electromagnetic spectrum. X-Rays are part of the electromagnetic spectrum and have the highest frequency..
Electromagnetic waves don't come in different types. They are all the same physical phenomenon, they all have the same speed in space, and they all exhibit the same electrical and optical behavior. Depending on their wavelength (frequency), we may call them radio, microwave, heat, infrared, visible, ultraviolet, soft x-ray, hard x-ray, or gamma ray but these are all simply different regions in the continuous distribution of the same phenomenon.

Electormagnetic (EM) waves are all the waves and subsequent wavelengths that make up the Electromagnetic Spectrum. This includes but is not limited to: Radio Waves Infered Waves Visible Light Micro Waves X- Rays If you want a complete list look up the Electromagnetic Spectrum.

X-rays have the highest frequency in the electromagnetic spectrum.
Radio Waves are in the lower end of the electromagnetic spectrum and have wavelengths between several hundred feet (AM Radio) to fractions of an inch (Microwave communications). X-Rays are high energy photons at the upper end of the electromagnetic spectrum, with wavelengths shorter than visible light, measured in nanometers to picometers. Color wise, Red is the longest visible, while Violet is the shortest wavelength of visible light. There are many graphical charts of the electromagnetic spectrum that show where the various waves fit in relation to each other, these can be found on an internet image search.
The list of electromagnetic spectrum with an increasing wavelength is given: Gamma rays X rays Ultra violet Visible Infra red Micro waves Radio waves. Now you yourself can pick the needed answer.
sound does not belong to the list.
Alpha, Beta, Gamma and cosmic are all examples of radiation.Types of radiation could be:Ionizing radiationElectromagnetic radiationInfra red radiation
The sequence of the listing in the question is correct. From longest to shortest wavelength, these four categories of EM radiation do in fact list in the order: 1). infrared 2). visible 3). ultraviolet 4). X-rays
