Phys 201 Multiple Beam Interference 3

Summary

Manipulate the summation to make a geometric series - the summation can be removed! Apply Stokes Relation to get down to just one coefficient: r. To deal with the infinite reflections, write their coefficients in a systematic way to express it with a summation. Here are some mathematical musings on why Of course, we observe irradiance, so here we square the complex field to calculate it. The phase term includes wavelength and angle, which explains the colors. The square of the summed fields leads to a cross term, called the " If you have your IB Diploma exams in May 2026, we have intensive revision courses designed to help you feel much more ...
