Radiowaves, microwaves, infared waves, visible light, ultraviolet, X-rays, and gamma rays. 1 of 7 Where is ultraviolet found naturally? Ultraviolet radiation - UV - is found naturally in sunlight. 2 of 7 What can microwaves be used for? Microwave radiation can be used to transmit signals such as those for mobile phone calls. 3 of 7 How can white light be split up? White light can be split up to form a spectrum using a prism. 4 of 7 Light waves are refracted as they enter and leave a prism. What colour is refracted the least and what is refracted the most? Red light is refracted the least and violet light is refracted the most. 5 of 7 How can microwaves affect the body? Microwaves can cause internal heating of body tissues. 6 of 7 How can X-rays and gamma rays affect the body? X-rays damage cells causing mutations (which may lead to cancer) and cell death. Gamma rays also damage cells causing mutations and cell death. 7 of 7
