Infrared Radiation

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
