Radiation

• What do all bodies (objects) emit and absorb?

  Infrared radiation.
• What happens to the quantity of infrared radiation emitted by an object as temperature increases?

  The hotter the object, the more infrared radiation it will emit.
• What happens to the type of radiation emitted by an object as temperature increases?

  The hotter the body the shorter the wavelength of radiation released (e.g. x-rays and gamma rays).
• Intensity and wavelength distribution of any emission depends on temperature.
