The region of visible light does vary from person to person with the range extending from    to . Ultraviolet Waves are part of the electromagnetic spectrum. Night sights on advanced weapons use this method. There are no precise accepted boundaries between any adjacent portions so the ranges do overlap. WiFi, radar, mobile phones, satellite communications…) From the lowest frequency to the highest frequency they are: Each of these waves have their own uses and dangers and are also produced using different methods – as outline below: Post was not sent - check your email addresses! », Alpha, Beta, Gamma. Registered office: International House, Queens Road, Brighton, BN1 3XE, Electromagnetic Spectrum - Uses and Dangers, The uses for this are obvious, we use light waves in order to see things. The crucial aspect to not overrule in this case is the fact that all AM waves travel at the same speed in a vacuum. Get Revising is one of the trading names of The Student Room Group Ltd.

Einstein’s Equation and the Photoelectric Effect, To understand the electromagnetic spectrum and the properties of electromagnetic waves, To learn the order of waves in the electromagnetic spectrum the principal radiations from radio waviest gamma rays, To onderstaand the uses and dangers of the waves in the electromagnetic spectrum. • Shorter waves – for TV and FM radio cannot be reflected – need to use satellites to reach distant parts of the world. Grade 9-1 GCSE Physics worksheets, past papers and practice papers for Edexcel, AQA and OCR. Further notes: Radio waves and microwaves; These two parts of the spectrum share a lot of similarities and uses. Gamma rays are formed in the process of radioactive decay, fission or fusion, whereas X rays are not. Microwaves can be used to cook food, in a microwave oven.
