Hints for the Homework (check frequently for updates,
updated by Grader Tommy Lam)
(except on midterm and exam days): A quiz (closed book)
will be given at the beginning of each class.
consists of 2 short questions on materials covered in the
previous lecture and 2 short questions on the materials to be
covered that day. You will need your iclicker/or device
for the quiz. You
have one to two minutes to answer each question.
Grading is based on an absolute scale.
Total (100%) = quizzes/iclicker questions (15%) + HW (25%) +
(Midterm 1+ Midterm 2 + Final=(60%)).
The combined % for Midterm 1+ Midterm 2 +
Final=60%; the highest score=25%, middle score=20%, lowest
There will be two midterms and a final.
There will be four questions on each midterm, which will
be a combination of quantitative (3) and conceptual (1).
For the two midterms, you can bring a standard size
notecard with formulae.
*** Midterm I, Monday, October 16
(Problem 1: Interference;
Problem 2: Diffraction;
Problem 3: Special Relativity (remember
to study relativistic energy and momentum);
Problem 4: Short answer conceptual questions)
*** Midterm II, Monday November 13
(Problem 1: Photons; Problem 2: Particles behaving like waves;
Problem 3: Quantum Mechanics; Problem 4: Short answer/
Remember to study hydrogen-like atoms in the Bohr model,
the QM particle in a box, tunneling and
the Heisenberg uncertainty principle.
For the final exam (Monday, December 11th, 12:00-14:00)
you can bring a single sheet of paper with formulae.
The final exam will have 8 problems
(6 problems requiring
calculation and 2 short answer/conceptual questions
(including chapter 44)).
The last two problems
will include some questions about energy and momentum
in special relativity and particle physics.
Problem 1: Interference/Diffraction
Problem 2: Heisenberg Uncertainty Principle
(Particles and/or Waves)
Problem 3: QM I: Wave Functions
Problem 4: QM II: Atomic Structure
Problem 5: Molecules/Solid State
Problem 6: Nuclear Physics

There were 34 in-class quizzes in the
Fall 2016 edition of PHYS274. There will be a comparable
number in the Fall 2017 edition. However, these are fully
integrated into the lectures.
