Unit c heat & temperature notes(radiation)

1. Radiation

2. Radiation
• Radiation: Transfers heat through infrared
waves (same as light waves)
• Radiation is the only energy transfer that does
not rely on particle movement
• Radiant Energy: Energy carried through
radiation

3. Radiation
• What is our greatest source of radiant energy?
• THE SUN
• Heat from the sun cannot reach us by conduction or convection

4. Radiation
• The texture and color of objects can
affect how well they absorb radiation
• Dark materials absorb radiation better
than light materials
• Rough/dull textures absorb radiation
better than smooth or shiny materials
• Think of Foil!
