ELECTROMAGNETIC WAVE ELECTROMAGNETIC WAVE ARE WAVE THAT DO NOT REQUIRE A MODE CONTRACTION FOR THEIR PROPAGATION ELECTROMAGNETIC SPECTRUM 1.radio wave;this are radiation that are used to transfer signal from radio-stations to the radioset...its has the highest wavelenght. 2.infared;this electromagnetic radiation produces heat sensation and it is use for visiopn in the dark 3.visible light;this is the most radient energy that enables thing to be seen. 4.ultraviolet rays;this spectra is produced from the end of a visible violet ray,its affect photografic plates and makes some materials to florisent. 5.x-ray;this radiation has a high penetrating power and is is uses in agriculture to kill germs,to check cracks in materials in industries. 6.gamma rays;this electromagnetic spectrum is used to kill cancer and tumorscontinue reading
