A double slit produces a diffraction pattern that is a combination of single- and double-slit interference, where the first minimum of the single-slit pattern falls on the fifth maximum of the double-slit pattern. Find the ratio of the width of the slits to the distance between the slits.
If both 500-nm light and 650-nm light each pass through two slits that are separated by 0.50 mm, how far apart are the second order maxima for these two wavelengths on a screen 2.0 m away?
Two slits are separated by a distance exactly five times the width of the slits. How many interference fringes lie in the central peak of the diffraction pattern?
