Question
Two waves of the same wavelength interfere - in which case(s) below, will the two waves experience fully destructive interference? (Note: is "pi")
2.
What quantity/quantities change when a light wave move from air to water, and how does it/do they change? (Select all that apply.)
3.
The phase of a wave changes by 180 degrees (i.e., the wave flips) at a boundary when:
4.
You are looking at thin film interference due to a piece of glass (n = 1.50) in water (n = 1.33). Which of these n values would you use in formulas 17.14 & 17.15 and how many phase changes are you dealing with in this problem?
5.
You wish to design an anti-reflection coating optimized for a particular wavelength of light. For that wavelength, you want thin-film interference that is
6.
You are looking at two microscope slides with a very thin film of air between them. At a particular spot on the slide, you see red light reflected. That means that:
Two waves of the same wavelength interfere - in which case(s) below, will the two waves experience fully destructive interference? (Note: is "pi")
A) the two waves are 1.5 wavelengths apart in phaseB) the two waves are a half wavelength apart in phase
