Question: In a double-slit experiment, the wavelength of the light source is 520 nm, the slit separation is 35 um, and the slit width is 7 um. Find: What is sin(theta) of the first minimum diffraction envelope? How many bright interference fringes are within the central peak of the diffraction envelope? The value of alpha for the second bright fringe in the first minimum diffraction envelope is ? *pi. The value of beta for the second bright fringe in the first minimum diffraction envelope is ? *pi. What is the ratio of the intensity of the second bright fringe to the intensity of the central fringe?
