Infrared Radiation

HideShow resource information
What is Infrared Radiation?
All objects emit and absorb infrared
1 of 5
What are good absorbers?
Dark, matt surfaces – good absorbers, good emitters (this means that a dark, matt object will heat up faster or cool down faster than a light, shiny one)
2 of 5
What are poor absorbers?
Light, shiny surfaces – poor absorbers, poor emitters, good reflectors.
3 of 5
What affects the amount of Infrared Radiation emitted?
The hotter an object is, the more IR it emits in a given time (time is important!)
4 of 5
What does it use?
Infrared radiation is a type of electromagnetic radiation, which involves waves rather than particles.
