Light with a wavelength of 500 nm (nano means one billionth or ) is incident upon a double slit with a separation of m. The screen is located 3 m away from the double slit. At what distance from the center of the screen will the first bright fringe beyond the center-fringe appear?
Summary: First I derived expression for the position of mth bright fringe from the central maxima. Then I calculated the distance of 1st bright fringe from the central fringe.
