Electromagnetic spectrum
what each radiation does
Radio waves: communication and broadcasting
Microwaves: cooking and ssatellite
infra red: heating and night vision equiptment
visible light: optical fibre 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.
radio - Gamma ray the wave length decrease, Frequency and energy increases
visible light includes colours (Red, orange, yellow, green, blue, indigo, violet) (ROYGBIV) goes red- violet. Red having the biggest wave length and the smallest frequency and energy.
how each radiation can hurt you
Transverse waves.
light is part of a continuous electromagnetic spectrum
visible light: burning, blindness if concentrated
ultra violet- damage to surface cells and blindness
infra red: skin burns
x-rays:cancer
microwaves: internal heating of body tissue
gamma rays: cancer, mutation
Radio waves: safe unless at a very high concentration
