On 11 February 1800, (William) Herschel ... discovered infrared radiation in sunlight by passing it through a prism and holding a thermometer just beyond the red end of the visible spectrum... He was shocked when it showed a higher temperature than the visible spectrum. Further experimentation led to Herschel's conclusion that there must be an invisibleform of lLIGHT beyond the VISIBLE SPECTRUM.source:WikipediaWhite light is actually not a single colour. It is made up of lots of colours. The colours that you can convince yourself of seeing are red, orange, yellow, green, indigo, blue and violet. Each of these colours is actually a transverse wave. Becasue we can see them, we call this 'mini collection' of waves the 'visible spectrum'. Here's the note sheet on these 'visible' waves:The Waves of the Visible SpectrumSo, this is what Herschel did:Then, we tried it in the lab and here's the photo. The stick thing is a thermometer probe. We checked out the temperatures in the spectrum made by splitting white light with a 60° prism. Then we looked at the temperatures outside what we can see (to the left of the red in the photo).Repeating Herschel's experiment in the labAnd, much to our surprise, more than half of the class reported a higher temperature outside of the red part of the spectrum. If this is correct, we repeated Herschel's experiment in our lab. This 'unsee-able' colour is in fact a wave that we call today 'infra red'.The Electromagnetic Spectrum2.2 Demonstrate an understanding that all electromagnetic waves are transverse and that they travel at the same speed in a vacuum 2.3 Describe the continuous electromagnetic spectrum including (in order) radio waves, microwaves, infrared, visible (including the colours of the visible spectrum), ultraviolet, X-rays and gamma rays2.4 Demonstrate an understanding that the electromagnetic spectrum is continuous from radio waves to gamma rays, but the radiations within it can be grouped in order of decreasing wavelength and increasing frequencyElectromagnetic dangers2.5 Demonstrate an understanding that the potential danger associated with an electromagnetic wave increases with increasing frequency 2.6 Relate the harmful effects, to life, of excessive exposure to the frequency of the electromagnetic radiation, including:microwaves: internal heating of body cellsinfrared: skin burnsultraviolet: damage to surface cells and eyes, leading to skin cancer and eye conditionsX-rays and gamma rays: mutation or damage to cells in the bodyUsing the Electromagnetic Spectrum2.7 Describe some uses of electromagnetic radiation radio waves: including broadcasting, communications and satellite transmissionsmicrowaves: including cooking, communications and satellite transmissionsinfrared: including cooking, thermal imaging, short range communications, optical fibres, television remote controls and security systemsvisible light: including vision, photography and illuminationultraviolet: including security marking, fluorescent lamps, detecting forged bank notes and sterilising waterX-rays: including observing the internal structure of objects, airport security scanners and medical X-raysgamma rays: including sterilising food and medical equipment, and the detection of cancer and its treatmentIonising radiation2.8 Recall that ionising radiations are emitted all the time by radioactive sources 2.9 Describe that ionising radiation includes alpha and beta particles and gamma rays and that they transfer energy
All types of cameras, pinhole and those using optical lenses, use light which is an electromagnetic radiation

Microwaves are part of the electromagnetic spectrum which are not visible to the unaided human eye, hence, without scientific research we would never know that microwaves exist.
UV is a type of radiation. It is fatal for life on earth.
Yes.
i dont know i was asking you
it relates to radiation because they contain electrons which is radiated
UV is a type of radiation. It is the fatal radiation of the sun.
The best answer I can think of is "gauge particle." "Speed in a vacuum" is another possibility. The below, while true, does not really answer the question asked. ---- First, I have to explain radiation. Radiation consists of three types: alpha, beta, and gamma. Alpha radiation is destructive and is comprised of a helium nuclei, or two protons and two neutrons. Beta radiation is either an electron or a positron (I would read other sources for better information on this, it does not relate to the question). All of the rest, including gamma rays, are waves included in what is known as the electromagnetic spectrum. The sole difference is their wavelength, or distance between repetitions in the wave, and frequency, the time it takes for a certain number of wave units to pass a certain point, often expressed in waves/second, or Hertz. The electromagnetic spectrum and its components can be more thoroughly explained by other sites.
