Light passing two glass plates, physics problem. HELP please?!

[From: ] [author: ] [Date: 12-04-21] [Hit: ]
will the transmitted light be bright?-What you are describing is a version of something called a Fabry–Pérot interferometer.You need to read about it to get the full picture. Look at the section called Fabry-Perot Geometry near the centre of the link.You get maximum transmission when adjacent exiting rays are in phase.α=0 so cos(α)=1.......
A beam of light of wavelength 569 nm passes through two closely spaced glass plates, for what minimum nonzero value of the plate separation, d, will the transmitted light be bright?

What you are describing is a version of something called a Fabry–Pérot interferometer. You need to read about it to get the full picture. Look at the section called "Fabry-Perot Geometry" near the centre of the link.

You get maximum transmission when adjacent exiting rays are in phase. Using the formula provided in the link:

2dcos(α) = mλ
α=0 so cos(α)=1. Taking m=1 gives the smallest value for d:
d = λ/2= 569/2 nm
