Mobile phonesuse microwaves, as they can be generated by a small antenna, which means that the phone doesn't need to be very big. Overexposure of our eyes to ultraviolet radiation can cause blindness, so we should wear hats and sunglasses on sunny days. The electromagnetic spectrum is made up of seven regions, all of which have their uses due to their relative wavelengths. The electromagnetic spectrum is the range of all frequencies of electromagnetic radiation which includes visible light as well as invisible radiations like radio waves, infrared rays, gamma rays.Electromagnetic radiation from the spectrum has found multiple applications ranging from communication to manufacturing. Thank the "visible" spectrum. Ultraviolet radiation - UV - is found naturally in sunlight. Left: Portrait of Wilhelm Conrad Röntgen who is credited with discovering X-rays. The higher the frequency of the radiation, the more damage it is likely to cause to the body: Microwave radiation can be used to transmit signals, such as those for mobile phone calls. All EM waves are made up of photons that travel through space until they interact with matter; some waves are absorbed and others are reflected. Longest wavelength and lowest frequency starts Radio waves, microwaves, infrared, visible light, ultraviolet light, x rays, gamma rays Edited by Jamie (ScienceAid Editor), Taylor (ScienceAid Editor), vcdanht, Sim and 4 others.
