2. Vocabulary Foldable Cut only 1 side! Fold your paper in half
Fold your paper into four sections
Cut only 1 side!
This will create 4 flaps

Definition
Example
Refraction
Transmission
Absorption
Reflection

4. Reflection
Definition: light waves bounce back after striking a surface that doesn’t absorb all of the wave’s energy Colors that we see are visible light waves that are reflected off an object

5. Absorption
Definition: light waves enter a material and do not come back out
HOW? Electrons in atoms can absorb various frequencies of light causing the energy to be absorbed and turned into heat energy.
Are there any examples of absorption in this room?

6. Transmission Definition: Light waves pass through a material
HOW? Light waves cause electrons to vibrate and are passed on along to neighboring atoms through the medium to be reemitted on the opposite side
What kind of medium would we need for light waves to be transmitted through?

7. Refraction
Definition: Light waves bend as they pass from one medium into another.
Example- going from glass into the air as with a prism
Direction of wave
Direction of wave
What is an easier way to say refraction?

8. Do You Get It?
Explain what is happening in each picture. Use the vocabulary words from your foldable!
