Conceptual Break Unpolarized light that goes through a series of 4 polarizers, each 30 degrees offset will have zero intensity after the fourth polarizer since the first and last polarizing axes are perpendicular. To solve for a constructive interference on a diffraction grating, the formula dsin(θ) = mλ can be used. For diffraction, m denotes the center of the mth order maxima. The wavelength of the radiated photon is larger for an electron falling n=4 to n=3 than n=2 to n=1. 5/28/2018
