Physical Optics: Interference & Diffraction Here's my question: Two identical rectangular pieces of glass are laid on top of one another on a plane surface. A thin strip of paper is inserted between them at one end, so that a wedge of air is formed. The plates are illuminated by...

i got up to.. (n1)[sin(theta1)]=(n2)[sin(theta2)] where n1 = air n2 = my index (1)[sin(theta1)]=2.1[sin45] but the only problem is.. i know that this is wrong.. since (2.1)(sin45) is > 1.. and theta will be messed up on it.. I know it has to do with something with the geometry...

Here's the question: http://www.geocities.com/rhack_/physics.jpg I'm doing a CAPA (Computer Assisted Personalized Approach) - basically online assignments. So.. here's one of my questions.. I know that... in order to have total internal reflection, the angle of incidence for the first...
