Module 5: Interference, Diffraction

Home Syllabus Modules Schedule Laboratories


Students will study the phenomena and the mathematics of interference and diffraction.  They will become familiar with optical instruments based on these phenomena.  Students will be able to describe the essential features of a LASER.  They will understand a laser as an electromagnetic oscillator which combines light amplification with feedback.  Students will be able to describe the characteristics of several laser system, such as He-Ne lasers and diode lasers.  Students are expected to study the material presented in the textbook and the Web material.
