Consider a Young's two-slit experiment in which the wavelength of light is 45% smaller than the distance between the slits. How many complete dark fringes would be seen on a distant screen? (Assume for all these questions that the screen is as large as it needs to be.) How many total interference maxima would be seen on a distant screen? Now suppose that the wavelength of light is 126% larger than the slit separation. How many complete dark fringes would be seen on a distant screen?
