 section 3THE ELECTRO MAGNETIC SPECTRUM
Definition
 the electromagnetic spectrum includes radio, microwave, infrared, visible, ultraviolet, x-ray and gammaray radiations• radio waves: broadcasting and communications;• microwaves: cooking and satellite transmissions;• infrared: heaters and night vision equipment; • visible light: optical fibres and photography; • ultraviolet: fluorescent lamps; • x-rays: observing the internal structure of objects and materials and medical applications; • gamma rays: sterilising food and medical equipment
Term
 section 3LIGHT + SOUND
Definition
 light waves are transverse waves which can be reflected,refracted and diffractedthe difference between analogue and digital signals is that a digital signal is either on or off whereas an analog signal can be 'in the middle'the frequency range for human hearing is 20 Hz – 20,000 Hzan oscilloscope and microphone can be used to display a sound wave
