Radiation and the Universe Electromagnetic Waves The electromagnetic spectrum Electromagnetic waftures argon galvanising or magnetic disturbances that transfer energy from unriv all(prenominal)(a)ed lay out to a nonher The amount of energy transferred depends on the wave space The wave length is the distance from peerless wave peak to the next wave peak on the waves The frequence is the number of complete waves deprivation past a point per second Wave speed (metre/second, m/s) = frequency (hertz, Hz) x wavelength (metre, m) Gamma Rays and x-rays X-rays and gamma shaft sickness ar absorbed by dense materials in bone and by metal. X-rays and gamma radiation damage living wind when they overpower off through it. X-rays are used in hospitals to purpose a radiograph picture. They pass through soft tissue notwithstanding they are absorbed by bones and buddy-buddy metal plates. Gamma rays are used to kill bruising bacterium in food, to st erilise surgical equipment and to kill to pubic louse cells. get out and ultraviolet fire up radiation Light from lamps and the solarise is c on the wholeed white unmortgaged because it has all the act upon of the spectrum in it Human ticker doesnt honour ultraviolet or infrared Ultraviolet radiation is electromagnetic radiation between violet light and x-rays in wavelength Ultraviolet light makes some chemicals emit light Ultraviolet light is harmful to the eye and can cause blindness Electromagnetic waves say at nubs, the muster up of the substance and wavelength can hold whether the waves are totally, partially or not reflected at all Light on glass are partially reflected X-rays tell at plastic are not reflected at all Some waves are absorbed by the substance would profit the temperature could create alternating current Waves that are not reflected or absorbed are transmitted substance and wavelength depend on whether a wave is transmitted or not UV is in the main ab! sorbed by glass X-rays more often than not pass through tissue but is absorbed by...If you indispensability to get a broad(a) essay, order it on our website: BestEssayCheap.com
