Year 9 Electromagnetic Spectrum independent learning task The visible spectrum is only a small part of a wide group of electromagnetic waves. In order from smallest to largest wavelength, these are; gamma rays, X-rays, ultraviolet waves, visible light, infra-red waves, microwaves and radio waves. These make up the electromagnetic spectrum. Though we cannot see these other types of waves, they can be detected and are used in a variety of applications. Short wavelength Long wavelength High frequency Low Frequency Your task is to put together a presentation of the uses of the electromagnetic spectrum. For each of the following: Gamma rays X – rays Ultraviolet rays Visible light Infrared rays Microwaves Radio waves Describe and explain: 1) 2) 3) 4) 5) Uses Sources Dangers Pictures Other information Use the following websites as starting points: http://missionscience.nasa.gov/ems/01_intro.html http://science.hq.nasa.gov/kids/imagers/ems/index.html http://imagine.gsfc.nasa.gov/docs/science/know_l1/emspectrum.html http://www.bbc.co.uk/schools/gcsebitesize/science/aqa/waves/soundandlightact.shtml Image: Whalley, K.
