Note: Answer Keys for Exams 1 and 2 are below.

                                                                                   General Remarks

A. Check into this page for announcements and items I may have forgotten to mention in class. If you think some course-related information is missing from this page, contact wsaslow@tamu.edu

B. Why this subject matter is an essential part of the science and engineering curriculum:

Around 1865, James Clerk Maxwell unified the separate subjects of on the one hand, Electricity and Magnetism, and on the other hand, Light. 

He predicted that oscillations of the coupled Electric and Magnetic fields can propagate through space at any frequency, and that what we see as Light (some 10^{15} cps) is such an oscillation.

When Maxwell's theory of Electromagnetic Radiation was 22 (in 1887) these oscillations were observed by Heinrich Hertz at microwave frequencies (some 10^{12} cps).  EM Radiation includes, in order of increasing frequency, Microwave Radiation, Infrared Radiation (IR), Light, Ultraviolet Radiation (UV), x-rays, and gamma-rays.

Within ten years of Hertz's work, Marconi had developed the radio; this marks the beginning of modern wireless communications.  We owe a deep debt of gratitude to Maxwell for predicting EM radiation, which we now use in radio, TV, cellphones, wireless connections to the World Wide Web, etc. 

All forms of electromagnetic radiation, whether carried through the air or along cable, are summarized mathematically in Maxwell's Equations, and all areas of science and engineering associated with electromagnetic signals have their basis in Maxwell's Equations.

C. Make sure that you get the names, addresses, and emails of at least three others, to form a study group. Make sure you are part of a study group.
