COURSE: PHYS 227 - OPTICS AND MODERN PHYSICS

INSTRUCTOR: Dr. Fearn

TEXT: "Fundamentals of Physics 3rd Edition", by Halliday & Resnick, Wiley.

The following books might be useful and can be found in the library;

Optics by Hecht,

Special relativity by A. P. French,

Introduction to special relativity, by R. Resnick.

Quantum mechanics by Liboff

Intro to the quantum theory, by Park

Feynmans Lectures on Physics are always useful.

EXAMS/PROBLEMS:

There will be 2 midterms, and a final each worth 30% of the final grade. The midterms are on Optics, Relativity and and the final is on Quantum Mechanics. Problems will be given to you in xerox form. These account for the remaining 10% of the course. Solutions will be displayed on the 6th floor and available for copy in the dept office. No late problems will be accepted. Fact sheets issued by the instructor are used in the exams. Not all the needed formulae will be on them. Copies of the fact sheets will be made available prior to the exams, you cannot bring your own copy to the exams.

No makeups for the final (only for EXTREME EMERGENCY). Show up for exams even if you are late, every effort will be made to give you the full time, but I will not guarantee that. The lowest problem sheet score will be dropped. No show for an exam without prior notification will be graded as a zero.
