I really want to listen to this podcast but it does not work with my iPhone 4 & the latest OS. Please address this.

This is a straightforward yet comprehensive course on the physics of light and optics with a foundation in EM theory. Well-taught, the concepts are readily grasped from the lecture even without the benefit of the course text or video of blackboard notes. The subject matter includes both theory and practice, including introductions to important and useful devices. This podcast is especially well-suited to new students, with some episodes quite useful to the experienced professional who wishes to conveniently and quickly review basic details of specific subjects in this field. At the time this review was written, the video episode (lecture) on the Wave Equation was missing audio; whatever could be done to fix this problem would be most welcome.
