Radiation is the last but definitely not least of the ways in which heat transfers and moves from one place to another. The Earth's largest contributor of energy is the SUN! The sun sends out heat energy in the form of radiant energy waves. The two main energy waves are known as Ultraviolet A and Ultraviolet B. Radiation does NOT require particles to move through the atmosphere (Thank goodness for that or we'd be popsicles!). Instead heat just moves in waves! Much like how sound and light travels in waves.
These radiant energy waves are what makes us feel warm but it is also what causes us to burn if we are out under the sun for too long without protection.
Certain types of surfaces will absorb or reflect radiation waves. Record down some examples of different surfaces that 1) absorb heat radiation more than others, and 2) reflect radiation more than others.
Copy a diagram of the radiometer and explain how it works.
