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
