Waves Applications

Question 1

Radio wave application

Answer 1

Transmit radio + tv signals
Can travel long distances before they’re absorbed by trees / buildings
Can spread out between hills

Question 2

Microwave application

Answer 2

Cooking food / satellite communications
Able to heat up water molecules that food contain as they absorb microwave energy
Can pass through atmosphere without being refracted / reflected

Question 3

Infrared applications

Answer 3

Electrical heaters / cooking food / infrared cameras

Energy emitted by infrared is easily absorbed by surfaces of objects

Question 4

Visible light applications

Answer 4

Fibre optic communications

Short wavelength + carry’s a lot of info

Question 5

UV light applications

Answer 5

Energy efficient lamps / suntanning
Short wavelength = more energy carries than visible light
Can be absorbed / converted to visible light = more energy efficient than normal light bulb

Question 6

X-rays applications

Answer 6

Medical imagine
Absorbed by bone = can see white parts on images (bone)
Penetrate = passes through body tissue easily

Question 7

Gamma rays applications

Answer 7

Detect cancer + treatment

Penetrate = passes through body tissue easily
