The two slits of a double-slit experiment have widths in the ratio $4 : 1$ , so they give intensities in the same ratio. What is the ratio of the brightest to the darkest intensity in the pattern?

← All Quizzes

← A double-slit experiment in air gives a fringe width β. The whole apparatus is then put under a liquid of refractive index 1.35. Which change brings the fringe width back to β?A narrow slit is lit by a laser, and the pattern is seen on a screen. Which change makes the central bright band wider? →
