When light is absorbed,...

• the light is reflected from the object.

• the light energy is changed into heat energy.

On a hot day, which would you choose to walk across barefoot?

• 
• 
• 
• 

Why is a road hotter to walk across than the other surfaces?

• The road reflects the most light back to your feet.

• Because it is black, the road aborbs the most light and the absorbed light turns into heat energy.

• The road gets hot because of the exhaust from cars.

• The road isn't hotter than other surfaces, they are all the same because they get the same amount of light.

• 
• 
•
