What is electromagnetic spectrum? Explain the different type of electromagnetic wave. What are the uses of Gamma rays? What are the uses of X rays. What are the uses of ultraviolet rays? What are the uses of visible rays? What are the uses of infrared waves? What are the uses of micro waves? What are the uses of radio waves?
All type of electromagnetic wavelength is arranged in order of increasing wavelength or decreasing frequency is called electromagnetic spectrum. Gamma waves are used in cancer and tumor treatment. They are also used to preserve the food items. Gamma rays are also used to study nuclear reaction. X-rays are used to detect the facture in bones. These radiation are also used to detect explosive and to study the crystal structure by x ray deflection technique. Ultra violets rays are harmful rays are harmful radiation and are absorbed by the ozone layer. However they are used to purify water and preserve the food stuff and to detect finger prints or forged documents. Visible rays are used by our eyes and make things visible to us. Plants also use it for photosynthesis. Infrared radiation has heating propery and is used in all heating devices. Micro waves are used to detect the speed of moving vehicle, cricket ball, and tennis ball. And as the name suggest it is used in micro wave oven for cooking purpose. Lastly, radio waves are used for all kind of communication.
