Infrared waves part of EM Spectrum
All objects emit infrared radiation
The hotter an object is the more infrared radiation it emits in a given time
Infrared radiation can travel through a vacuum (energy from the sun)
Surfaces And Radiation
Good Absorbers of Infrared Radiation: Dark, matt surfaces.
Good Emitters of Infrared Radiation: Dark, matt surfaces
Good Reflectors of Infrared Radiation: Light, shiny surfaces
States of Matter
Solids, Liquids and Gases.
Solid: Particles vibrate in fixed positions, maintains a fixed shape.
Liquid: Particles in contact with each other but can move about randomly, no fixed shape & can flow.
Gas: Particles far apart and can move freely much faster, no fixed shape & can…
