What emits IR radiation
Everything emits IR radiation
1 of 8
The effect of temperature on the amount of IR raditaion emited
The higher the temperature the mor IR radiation is emited
2 of 8
5 more facts about IR radiation
1. IR radiation cannot be seen 2. IR radiation CAN be felt 3. IR radiation travles in electro magnetic waves 4. IR radiation can travle through a vacume 5. IR radiation can be reflected and absorbed
3 of 8
What difference does surface colour have on IR radiation
There is a small amount of difference between emisions of IR. Shiny surfaces can hold heat better/ for longer so black is a better emitter of radiation than silver
4 of 8
Six uses of IR radiation
1. An electric iron 2. An elecric fire 3. Grilling/ toasting food 4. Thermal imaging 5. The back of a fridge 6. A heat sink in a computer
5 of 8
How are cold objects heated up by their surroundings
Cold objects absorbe IR radiation just like hot objects emit it
6 of 8
Two uses of good absorbers
1. Dark winter clothes 2. Solar heating panles
7 of 8
Four uses of good reflectors
1. Light summer clothes 2. Houses bainted white in hot contrys 3. Shiny silver fire fighter suits 4. Cricketers uniforms - they are out all day in summer
