A real double slit, consisting of two slits with finite widths, produces a diffraction pattern that is a combination of the interference due to a single slit and the interference due to an idealized double-slit (consisting of two slits of infinitesimal width). Find the ratio of the width of the slits to the separation between them that will produce an interference pattern such that the the first minimum of the single-slit pattern falls on the fifth maximum of the idealized double-slit pattern. (This will greatly reduce the intensity of the fifth maximum in the real double slit interference pattern.)

Alinearly polarized electromagnetic wave has an average intensity of 196 w/m^2. this wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). polarizer a is oriented with its transmission axis at an angle of θ_1=20.8∘ with the incident electric field. polarizer b has its axis at an angle of θ_2=63.0∘ with the incident electric field. what is the average intensity of the wave after it passes through polarizer a? what is the average intensity of the wave after it passes through polarizer b? suppose that the two polarizers a and b are interchanged. what would the average intensity be after passing through both polarizers?
