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

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 be taking a quiz about everything since August. This is a data gathering tool, so it will NOT hurt your grade. However, to encourage you to take it seriously, if you earn above a certain cut score I will give you extra credit.

Your unit test is on your next modular day. Below you will find a link to the practice test as well as a key.
