Assignment 5b May 9, 2008 1. A beam He-Ne laser (632.8 nm) is incident on a Fabry-Perot apparatus. Two coated plates with reflectivity 0.90 are at a distance t=1mm. We assume there is not energy absorption by the plate. (a) Plot the transmission as a function of the incident angle varying in the interval (0.2, 1.0) ° for the laser beam. (b) Calculate the angular positions of the maxima and of the minima to left and to right of the maxima and the

Calculate the minimum spacing between the plates of a Fabry-Perot interferometer which would resolve two light waves with wavelength difference 0.01 nm at 500 nm. Assume the reflectivity R to be 0.9....
