Question

1: Reflection phase shifts I am giving you several situations that involve light traveling in one medium and either entering another medium or reflecting off of it. Tell me which of those reflection and/or transmission events produce a half-cycle phase shift (or a half-wavelength phase shift, in the language of Halliday and Resnick, Chapter 35, section 4), and which have no phase shift. 1. Light in air reflecting off glass (n = 1.5). 2. Light in air entering glass. 3. Light in glass entering water (n = 1.33). 1. Light in glass reflecting off water. 5. Light in high - index oil (n = 1.7) reflecting off glass. 6. Light in high-index oil reflecting off water.

Explanation / Answer

1) no phase shift
2) half cycle phase shift
3) half cycle phase shift
4) no phase shift
5) no phase shift
6) no phase shift
