Reflective Essay on Inter Professional Education

Electromagnetic Spectrum Concepts of Health Physics communicate waves You should k straightaway both(prenominal) of the properties and uses of tuner waves. Radio waves ar made by discordant types of sender, depending on the wavelength. They argon also given off by stars, sparks and lightning, which is why you hear interference on your piano tuner in a thunderstorm. Television and wireless Radio waves have get down frequencies and longer wavelengths than microwaves. They be utilize to transmit television and radio programmes. Television uses higher(prenominal) frequencies than radio. A radio programme suck upr does non require to be directly in view of the transmitter to receive programme signals. For low frequence radio waves diffraction lavatory surrender them to be received behind hills, although repeater ranges ar often used to improve the quality of the signals. The lowest frequence radio waves are also reflected f rom an electrically charged train of the upper atmosphere, called the Ionosphere. This means that they can reach receivers that are non in the line of sight because of the curvature of the Earths surface. [pic] Microwaves and radio waves in the atmosphere USE Radio waves are the lowest frequencies in the electromagnetic spectrum, and are used mainly for communications.

Radio waves are divided into:- [pic]Long Wave, close to 1~2 km in wavelength. The radio station Atlantic 252 broadcasts here. [pic]Medium Wave, around 100m in wavelength, used by BBC Radio 5 and other AM stations. [pic]VHF, which stan ds for in truth exalted relative frequency! and has wavelengths of around 2m. This is where you find biaural FM radio stations, such(prenominal) as BBC Radio 1and Further up the VHF stripes are civilian aircraft and taxis. [pic]UHF stands for Ultra High Frequency, and has wavelengths of slight than a metre. Its used for Police radio communications, television transmissions and troops aircraft radios - although military communications are now mostly digital and encrypted.
