Question

106.=> As shown in figure, a two slit arrangement with a source which emits unpolarized light. P is a polarizer with axis whose diraction in not given. If Io is the intensity of principal maxima when no polarizer is present, calculate in the present case, the intensity of the principal maxima as well as of the first minima.
