We will start doing some sort of brief quiz every day. The first of these will be on Thursday, March 29, and the topic of that will be the remainder of the Quantum Physics unit, including the Photoelectric Effect. On later dates, including April 9, I will give some indication of the topics covered on each daily quiz. Quantum Physics will be completed on March 29. April will revisit certain older topics and do AP Exam review.

 

The course final exam will be on Thursday May 3. It will be a simulated AP exam. You will review for it early, as you would for successful AP exam performance. Materials for AP mock testing will be coming soon. The real AP exam is the week after the final.

 

You have all of your Quantum Physics materials on paper and online, so complete your study and reading of that unit by March 27.

 

We'll do something graded with the Photoelectic Effect on PhET, and I'll explain that in class on 3/27. So study the topic ASAP.

 

Read Chapter 28. I said that over a week ago. If someone asks me "is such-and-such gonna be on the test", I won't answer, because if it's not in Chapter 28, it won't be on the test. So I've already answered the question.

 

To do the practice quiz with 2016 in the title, you'll need to find your textbook's story on something called the Photoelectric Effect. You'll need to read about that in the semester soon anyway, so why not now? If you choose not to, you might not be able to take advantage of the 2016 practice test attached.

 

"A Modest History of Modern Physics" is a paper I wrote some years back. It doesn't deal exclusively with Chapter 28, but can give perspective, and also includes a little bit of additional Chapter 28 practice if you have time for it. You'll be reading it soon in the class anyway.

 

Chapter 28 Book Problems I like: 11 through 26, 44 through 50

 

The pdf file contains a Problem 7 to use for practice, Parts a and b only. Consider this part of the attached file named "Bohr Energy Quiz". Bohr Energy Quiz Key will tell you the answer to Problems 7a and 7b from the pdf. I do not like the College Board's key for the pdf problem 7. It's conceptually misleading.

 

To go with this, you're emphasizing in the textbook the reading of pages 786- 797.

 

And some templates for Ray Tracing attached - The filenames say "Ray Tracing Homework" but I'm not collecting ray tracing on 2/14. That doesn't mean don't do them though. They're good study aides. The homework that you have to do for me is described in the Study Guide attachment.

Are you also using this site?

 

 

Sample FR Questions from the years 2015, 2016, 2017, and examples of how to score them.

 

Just like the site I showed you months ago?

 

 

This is why I feel you've had no shortage of practice items since I told you the topics in December.

 

I'll make one more MC test available in class on Tuesday. One that I'm not allowed to post online.

 

Any files I attach here are powerful for giving more tries at the types of things that were available on Tuesday. On Thursday, 1/11, what you do with demos like these will count for credit.

 

Use Lenz's Law Discovery Template when you go through the step-by-step analysis of "Hovering Ring", of "Inducing a Current by Removing The Bar Magnet", of "Motional EMF", Page 1, of "Bar Magnet Falling Into A Copper Pipe", of "Bar Magnet Falling Out of A Copper Pipe". Notice these last two don't have worksheets. You've seen them enough time. You diagram and answer for their template quantities after you've done the "Hovering Ring" and "Inducing a Current by Removing The Bar Magnet" to get the hang of the communication process.

 

Before you do "Inducing a Current by Removing The Bar Magnet", you have to understand what's in "Interpreting The Meters Correctly To Know The Flow".

 

"Lenz's Law Discovery Template" is to be used right away.

 

"Lenz's Law Application Template" is not to be used until it's time. You will know.

 

The one called "Diagnostic Definition Comprehension Quiz" has its key in the same file as the original questions.

 

These cover a lot of good things, and why stop there. You know the Study Guide has even more questions from out of the book, and I posted a file with all the even answers from Chapter 19 book practice that I had placed on the Study Guide. So I hope each person uses what I gave.

 

Here is one more for you. "Wire on Wire". I said in class I'd give this to you to supplement the activity in class where a wire running current magnetically attracted or repelled a second wire also flowing current.

 

(By the way, Wire on Wire is the key analysis that proves why magnetic poles are NOT fundamental.)

 

The Practice Quiz entitled "Field Comprehension Check - 3 Basic Sources", asks questions about the strength of field inside the solenoid. Did you think that was unknowable or optional just because I didn't state it in class? That would be an untrue statement. Did you read Chapter 19 as instructed until you knew the meaning of the formula for the magnetic field inside a solenoid, and how to use that formula. (The text has good pictures; it makes it clear, and you know what a solenoid looks like, because you used them in my room.) In my experience, a minority of people become aware of the meaning of this particular solenoid formula even when directly instructed to find out about it, and I know that this is because a minority of people read with sufficient depth, physically defining every symbol without exception. It's your job to be outside of this unfortunate norm. FYI: my lab solenoids have 540 circles (AKA turns) of wire fit into a column that's 15 cm tall.

 

Summation: yes, I did assign knowing the solenoid, because I said to read Chapter 19. I could tell you the page it's on right now, but I won't, because everyone can read.

 

About "Velocity Selector Lecture Problem": That was a cool little practice quiz also posted on December 27 (and re-attached here). I've attached some things to this posting for that:

 

1) The key to Velocity Selector Lecture Problem BUT don't necessarily open the key if you didn't know what to do on "Velocity Selector Lecture Problem". How come? See #2.

 

2) Remember in class one day when I gave you the multipage document called "Velocity Selector Solution Breakdown"? Well, I did. This is a long discussion that talks about every possible important thing that in the end shows how simple the Velocity Selector's final solution is. Anyway, you were already given that file, and it's re-attached to this post. It reviews electricity as well as magnetism.

 

Attached are some Multiple Choice Sample Tests. For now, answer what you know on them to get the feel for the thinking involved. Many of the topics on these will be things on your exams, but some will be old review, and then there will be some things not covered yet. But just do it for now to measure what you can do.

 

This is to get you used to CollegeBoardish exam questions in multiple choice. (There will be some multiple choice questions on the final taken from old AP exams.) See how it goes. I posted exams from 1993 and 1998. Do this early. This is set up for you to see early, and then we go over in class and then adjust. People who only use these multiple choice exams when the final is days away are people who get ZERO benefit from them.
