1. Review waves
Draw a weak, slow wave - What would it look like? Sound like? Feel like?
Draw a strong, fast wave- What would it look like? Sound like? Feel like?
How do visible light waves work? What color has slow frequency waves? What color has fast frequency waves?
2. Doppler Effect Simulation
What are the lines coming from the Sun? What can these lines represent?
Describe the waves when both the sun and observer are still. What could change this?
What happens when the...
Sun moves toward the observer?
observer moves toward the Sun?
Sun moves away from the observer?
observer moves away from the Sun?
3. Examples of the Doppler Effect - Draw and explain
A. Ambulance Siren - Sound waves moving toward and away
B. Police Radar- Radio waves from radar gun
C. Motion of Stars and the Universe- Visible light spectrum
