- Everything since the last exam. This is reviewed with this:
- PRACTICE EXAM here and SOLUTIONS here. Formula sheet is here. If needed the following tables of hydrogen radial wave functions (only R(r) is necessary) and simple harmonic oscillator wave functions will be given.
- HW13 and material is not on the practice exam but could be on the final. Solutions are here
- Homework solutions for here and here and here and here
- Lectures on blackbody radiation and fermi gasses are here and here
- Homeworks since exam 2 are here and here and here and here. Roughly this covers chapter 9 and chapter 10.
- Exam 2 material is also going to be on the final. This is reviewd:
- Exam 2 is here
- Exam solutions and grading scheme is here
- Practice exam solution is here
- Practice exam is here
- Homeworks and Solutions are below. Exam 2 was based on homeworks 7,8,9. Homework 6 and more generally fourier series is not on the final.
- A statement of the objectives and the corresponding problems which will help you achieve those objectives for exam 2 material is here
- Integrals will be provided in general. For the practice exam look them up in the past homeworks
- From the first exam only the Bohr Model is on the final:
Course Organization
Overview
This course attempts to introduce the physics of the time period from1905 to 1940. Thus the name modern physics is perhaps a misnomer since it is more than seventy years old. Perhaps "introduction to a weird universe" would be a better title. In 1905 Albert Einstein (pictured below) deduced some aspects of this weird universe through a deep understanding of electricity and magnetism and classical mechanics.
The course will first introduce the basic notions of special relativity. Subsequently we will turn to quantum mechanics introducing the de Broglie wavelength and the photoelectric effect. Then we will study the Bohr model with an emphasis on estimates. Then we will investigate in detail quantum mechanics in one dimension. After this work we will begin to discuss the hydrogen atom and atomic structure . Finally we will give an brief introduction to the statistical mechanics of Blackbody radiation and Fermi gases.
Additionally this course will try to transition young scientists from elementary classes to more advanced junior and senior level courses. Fourier integrals will be introduced and Taylor series used constantly to develop an intuition for approximation and estimation.

Grade Determination
The grading will be based on the following table.
| Exam 1 | 30/15% |
| Exam 2 | 30/15% |
| Final | 35% |
| Homework/Recitation | 20% |
The 30/15% means that the highest of the two in class exams will be given 30% and the lowest of the two in class exams will be given 15%
Homework and Recitation
Recitation/homework is a major component of this course. Experience has shown that students who do not do the homework will not know what to do on the exams. Homework will be assigned in class (usually on Thursday) and randomly collected on Wednesday, i.e not every assignment will be graded. These assignments will graded primarily upon completion. During the recitation the assignment will be reviewed, and at the end a quiz will be given which will most often be taken from the assignment.
Some number of quizzes will be dropped (at least one and perhaps two.)

Physics 252 -- The Laboratory
PHY 252 (The Lab) is a separate course from PHY 251, and students earn a grade in PHY 252 separately from PHY 251. PHY 252 is required for Physics majors and majors must taken concurrently with PHY 251. It is not required by the Physics Department for students in other degree programs to take the lab. However the students should check if the lab is necessary for their degree program. All students may take the lab if they would like. Students who switch to the physics major may take the lab at a later date without taking the lecture.
Labs give you a chance to get a glimpse at some of the classic experiments which have either led to or confirmed important understandings in modern physics. Your lab instructor will describe the lab more, including when lab notebooks must be handed in and the penalties for late reports.
The laboratory manual will be provided week-by-week on the course web page. Print out a copy for yourself before each lab.
Policies:
-
If you miss a lab you will be allowed to make it up at certain time periods (see schedule below). For instance if you miss one of the first three labs you can make it up on the week 10/8. You will not be able to make up the lab after that. You must turn in your lab report the following week.
- The grade for the lab (PHY 252) is earned separately from the course grade, and will is based on the average of your best 8 lab scores. Labs not completed will not be dropped and will be given a zero.
-
The labs will not be accepted late. The lab instructor will sign your lab book and date it when the actual experiment is completed. If you do not hand in a lab on time you can make up the lab by redoing the experiment. Three labs can be made up for full credit.
Other Items
The Text Book
The book is Modern Physics, 3rd edition, by R. Serway, C. Moses, C. Moyer
Academic Honesty
Please read the statement on the undergraduate physics web page on student ethics and academic honesty. We will apply those standards to this class. `Disabilities
If you have a physical, psychological, medical or learning disability that may impact your course work, please contact Disability Support Services, 128 ECC Building, (631) 632-6748. They will determine with you what accommodations are necessary and appropriate. All information and documentation is confidential.Attendance
You do not have to come to class. But please try. During recitation a quiz will be given and homework will from be collected from time to time and so attendance is important (though some number of quizzes will be dropped).
