Where does infrared heat come from?
Infrared lies between the visible and microwave portions of the electromagnetic spectrum. Infrared waves that are near to visible light do not generate heat and are used in TV remote controls. Infrared waves that are far from the visible end of the light spectrum are thermal and generate heat. The infrared heat from the sun, a lamp or a radiator is a type of far infrared radiation.
What are infra red rays?
== == Infrared light lies between the visible and microwave portions of the electromagnetic spectrum. Infrared light has a range of wavelengths, just like visible light has wavelengths that range from red light to violet. "Near infrared" light is closest in wavelength to visible light and "far infrared" is closer to the microwave region of the electromagnetic spectrum. The longer, far infrared wavelengths are about the size of a pin head and the shorter, near infrared ones are the size of cells, or are microscopic.
How does UV light treatment work?
Ultraviolet (UV) light treatment is used primarily in cases of severe psoriasis that have not responded to other medications or in cases affecting large portions of the body.
How do you explain the different types of electromagnetic energy?
Electromagnetic (EM) energy is just one type of energy. It's a force in nature, and is one of the four fundamental forces we know of (along with gravity, and the strong and weak interactions, or forces). Let's look at how electromagnetic energy appears, and we'll do that by looking across the range of frequencies in which it is distributed. We call this distribution the electromagnetic spectrum, and we'll start at the bottom and work our way up. We'll remind you that low frequency means long wavelength and long period and low energy. Now let's get started. Lowest on the EM spectrum are the extremely low frequency (ELF) electromagnetic waves. We then see the super low (SLF), ultra low (ULF) and very low (VLF) frequencies. Then low (LF), medium (MF) and high (HF) frequencies, then very high (VHF), ultra high (UHF), super high (SHF) and extremely high (EHF) frequencies. All these frequencies of electromagnetic radiation are basically categorized as "radio waves" because that's primarily how we use them, what we use them for - for communications. Certainly the higher end of those groups of frequencies finds applications for other things in addition to communications, and the microwave oven is just one example. Things get more interesting as we go higher. Beyond the microwaves, those frequencies which we use in cell phone and satellite communications (among other things) we have what is called the infrared (IR) region. It's broken down into (in order of increasing frequency, which we've been doing) the far infrared (FIR), mid infrared (MIR) and near infrared (NIR) portions of the spectrum. These are all frequencies just below the optical spectrum, and thermal energy is transmitted fairly effectively by them. From here, we move into the visible spectrum. We're familiar with the red, orange, yellow, green, blue and violet of the optical spectrum. We call this visible light, and we just about take it for granted, don't we? (At least sighted people with good color vision do.) Beyond that is the ultraviolet (UV) region, with the near ultraviolet (NUV) and extreme ultraviolet (EUV) ranges within it. All that's left is the soft and hard X-ray (SX and HX) regions, and then the gamma (Y) region at the very top end. We're familiar with the X-rays and what they do, and the gamma rays, generated by changes in atomic nuclei, are just the extreme top end of the spectrum. Use the link below to do some review and look at some different aspects of the electromagnetic spectrum. Continue your investigation and discover how we generate and use these different frequencies of electromagnetic energy. You'll find more surprises than you can count.

Frequency and so wavelength
Who invented the electromagnetic spectrum?
You don't invent scientific facts - they are there for anybody to observe. You discover them. I believe Maxwell's calculations were groundbreaking in this sense; he calculated that an electromagnetic wave would move at the speed of light, and concluded that light was probably an electromagnetic wave, too. This was later confirmed. However, parts of the electromagnetic spectrum were later discovered by other scientists, for example, Röntgen.
