DETECTORS The detectors of the various radiations in the electromagnetic spectrum are i. Gamma rays - Geiger-Muller tube ii. X-rays - Photographic films iii. Ultraviolet rays - Photographic films, fluorescent substances iv. Visible rays - Eye, photographic film, photoelectric cell v. Infra-red rays - Skin, thermometer, phototransistor, photographic film. vi. Radio waves - Radio set, Television set, Aerials EVALUATION How can you detect the following radiations? (i) X-rays, (ii) Visible rays, (iii) Infra-red rays. Electromagnetic waves are regarded as transverse waves, why? USES A knowledge of infra-red rays is used in developing infra-red telescopes, infra-red signaling lamps which are useful to soldiers fighting in darkness. With the aid of photographic film which is sensitive to infra-red, it is possible to take clear photographs through mist and haze. X-rays are useful in hospitals (e.g., to inspect broken bones), industry (to inspect metal castings), and in science to study the crystal structure of matter. Gamma rays are used to kill cancer cells in a patient’s body as well as bacteria in foods and hospital equipment. A knowledge of ultraviolet rays is used in developing ultraviolet lamps, which are useful in conducting experiments on the photoelectric effect. Radio waves are very important for effective communication, especially when radio sets, television sets, and walkie-talkies are involved.
