Thin Film Interference

Описание к видео Thin Film Interference

This video will describe thin film interference. It is part of Topic 9.3 of the IB Physics Syllabus and is Higher Level material. The video starts with how and if a phase change will occur when light is reflected at a boundary. The conditions for constructive and destructive interference will be used to develop the equations needed to measure the thickness of the film. Finally, Snell's Law will be used to get the correct wavelength in the medium. There is a sample question at the end.

The simulation I used for the reflection of a wave can be found at:
