Objective: SWBAT identify how waves properties, wavelength and amplitude, impact the type and intensity of waves.
PS4-1: Use mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave.
Do Now:
Question 1
1.
A solar-powered toy moves when you shine a flashlight on it. Select all of the statements below that accurately explain how this happened.
Question 2
2.
What type of energy best identifies light energy? (PE/KE/No Energy)
(Think: Does energy from light move or is it startionary?)

Question 3
3.
What visual changes do you notice to the graph as frequency increases?
0
0
Question 5
5.
What visual changes do you notice to the graph as amplitude increases?
(THINK: Is the graph getting taller? Shorter? Are there more/less waves?

Question 7
7.
Model a wave that has a different intensity but the same color or type of light.
Question 4
4.
What visual changes do you notice to the graph as frequency decreases?
Question 6
6.
What visual changes do you notice to the graph as amplitude decreases?
