Exploring Light Waves: Key Concepts and Applications

The lesson covers light waves, focusing on reflection, transmission, and energy. Students learn how light interacts with materials, including absorption, reflection, and transmission. They are instructed to read and annotate an article, summarizing key ideas. The lesson concludes with a simulation assignment to explore light energy behavior.

Which type of light wave can be emitted from light source two?

• Wave C

• Wave D

• Wave A

• Wave B

When all colors of light are absorbed by a material, what color do we see?

• Green

• Black

• Red

• White

What should you do while reading the article about light behaviors?

• Highlight every sentence

• Summarize important ideas

• Skip paragraphs

• Ignore the visuals

What is the purpose of using hashtags in your annotations?

• To ignore the text

• Erase your notes

• Change your annotations

What is the key concept related to the movement of energy?

• Energy cannot be tracked

• Energy changes matter

• Energy is always absorbed

• Energy does not affect matter
