- Waves transport energy from one place to another (wave’s amplitude measures the amount of energy being transferred)
- Picture of wave which you have to label
- Big things tend to vibrate at low frequencies and small things tend to vibrate at higher frequencies
- Test will look like 2nd page of superposition worksheet
- Frequency, wavelength, and amplitude
- Going to ask for numbers on the test
- Draw 3 waves and the reflected wave
- Superposition
- Draw the paths of the 3 rays and 1 refracted rays
- Distance to get first max and then multiply by 4 to get wavelength. Frequency is given and find velocity
- Reverse arrows of Combined wave equation derivation (snell’s law) on the test
