P1 - Infrared Radiation
- Infrared Radition
- All objects emit and absorb infrared radiation.
- The hotter the object is, the more infrared radiation.
- Dark, matt surfaces are good absorbers and emitters.
- Light, shiny surfaces are poor
absorbers and emitters.
- Good reflectors of
radiation.
- Emitting Infrared Radiation
- All objects give out thermal radiation
- Matt black surfaces are the best
emitters of radiation.
- Shiny surfaces are the worst
emitters of radiation.
- Absorbing Infrared Radiation
- Infrared waves heat objects
that absorb them.
- Matt black surfaces are the best absorbers.
- Shiny surfaces are the worst absorbers.
- Because they reflect
most of the radiation
away
