Wave Interference and Reflection

Today we talked about what happens when waves overlap or hit a barrier/change mediums.

Notes
Simulations:
Zona Land Education: Wave Interference I
Zona Land Education: Wave Interference II
Zona Land Education: Wave Interference III
PhET: Wave on a String
Physics Classroom: Wave Interference Simulation

Homework: There is almost nothing to practice interference in the textbook, so your homework tonight is to play a game. Download the app Kerflux and get to at least level 30. Please note you do NOT have to pay anything for this game. If you do not have a device that can run Kerflux, that's okay too; I'm not actually checking this.

On Wednesday you will have a work day to prepare for your unit test.

Your unit test is next Wednesday, 2/26.
