Note on Fresnel transmission coefficient: Consider n1>n2 t>1 We still have conservation of Energy! Fresnel Coefficients:
Physics 123C Waves Lecture 9 Ray Optics. 2 Models of Light Is light a particle or a wave? Physics in the 20 th century has shown that this simple question.
Optics The light ray model A light ray is a line in the direction that light energy flows. My laser beam for example, is really a bundle of many parallel.
