Infrared radiation

• • Every object gives out (emits) infrared radiation
• • The hotter an object is, the more infrared radiation it emits at a given time.
• What effects how much infrared radiation an object gives out at a given time?

  The heat of the object
• Radio waves, microwaves, infrared waves, and visible light are all forms of electromagnetic radiation.
• Infrared radiation is energy transfer by electromagnetic waves
• Example of a perfect black body

  A) Radiation of any possible wavelength

  B) All wavelengths are absorbed

  C) No wavelengths are reflected or transmitted
