Physics Aviary Assignment - Modern Physics

1. Go to the Physics Aviary website.

2. Click the "Search" tab in the top row

3. Click "HW" from the Program Type drop-down menu

4. Click "Modern" in the Unit drop-down menu

5. Click "AP Physics 2" in the Class drop-down menu

6. Click Find Program

7. Complete the following Problems

Make sure you see the two notes below!!

--> Half-Life from a Graph

--> Half-Life from Data

--> Light From Atom

--> Half-life and Decay Constant from Data

--> Photoelectric Problem

Note!!!  In the Half-life and decay constant from data problem, it asks you to calculate the "decay constant."  The equation for this is: Half-life = 0.693/decay constant.  So, take 0.693 divided by your half life and that is the value of the decay constant.  The reason 0.693 is the number is that is the natural log of 2 - if you want to know why that is the equation, check out page 929 in the Giancoli.  You do NOT need to know anything about decay constant on my exam or the AP Physics 2 exam.  You do need to know what half life is and how to calculate it from a set of data or a graph.  Let me know if you have any questions.

Note #2!!!!  Looks like the graphing program is not really that great to solve the Half-life from Data problem on Physics Aviary.  Use Desmos or Logger Pro - the problem is pretty easy when you actually have a good graphing program.  Remember that I can send you Logger Pro for your Windows or Mac computer for free - it is a fantastic program to have if you are going into science or mathematics in college.
