Consider a Young's two-slit experiment in which the wavelength of light is 48% smaller than the distance between the slits.
A) 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.)
B) How many total interference maxima would be seen on a distant screen?
C) Now suppose that the wavelength of light is 145% larger than the slit separation. How many complete dark fringes would be seen on a distant screen?
