Physics the EM spectrum..?

Question

find examples of what the devices use the EM spec. and what can detect them .... EG

RADIO

uses: listinening to the radio

devices that can pick it up: radio when tuned into the right freuqency

i have that one but the rest are really hard for the devices bit someone help pls!

you have to find devices for

Microwaves

Infrared

Light

UV RAYS

X-rays

GAMMA RADIATION

Answer 1

Microwaves

Uses: microwave cookers are used to heating food / cook food.

Picked up by: in cookers it is the water molecules inside the food which absorbs the microwave energy heats up and cooks the food.

Microwave telescopes are also used to investigate the Big Bang. http://news.bbc.co.uk/2/hi/science/natur...

Infrared

Uses: Security systems, all living things emit heat which is seen as infrared light. This is the basis for security systems PIR (Passive Infra Red) detectors and night vision goggles.

Picked up by: Infrared cameras, and night vision equipment

Light.

Uses. Helps us to see. Plants can absorb light and use this to grow, photosynthesis.

Detected by. normal camera or photocell or your eyes.

UV Light,

Uses, humans need this to create vitamin D without which our bones go soft. (Strict Muslim women in the UK who cover up and get very little sunlight suffer from lack of vitamin D.)

Detected by. Fluorescent paint and T shirts glow at a disco when the UV lights are switched on. They absorb the light energy invisible UV light and re transmit it as several wavelengths of visible light.

X Rays.

Uses: Hospitals and engineering structures when one wants to see beneath an opaque surface.

Detected by Photographic film.

Gamma Radiation.

Uses, Mainly used in the food industry to sterilise food, killing bacteria and pathogens and making it possible for the food to be stored longer without it going rotten.

Detected by the Geiger counter.

Answer 2

Microwave cookers

Infrared telescopes

Light eyes micro amd tele scopes

UV sunlamps

X rays  medixal diagnostics using X-ray photos

Gamma radiation many radioactive devices using gamma in manufacturing controlling thickenesses of things

Not sure if this is what you wanred suspect not!
