1. Bellwork: What will happen when this ray of light hits this surface
Bellwork: What will happen when this ray of light hits this surface? Draw your prediction.

2. θf = angle of reflection
This is law of reflection – light will behave in this predictable way.
You need to know what this behavior looks like, and how to label it.
I = incident ray
R = reflected ray
N = normal line
θi = angle of incidence
θf = angle of reflection

3. θi = θr

4. θf = angle of refraction
3. When refraction occurs, light behaves predictable as well.

6. Let’s start reviewing the rest of the waves unit
Let’s start reviewing the rest of the waves unit. Try using “FPS – Wave notes”, “FPS – Waves Notes 2” and “FPS – Sound and Light notes”. When you’re done, text in on the board!
