Suppose you illuminate two thin slits by monochromatic coherent light in air and find that they produce their first interference minima at 35.25° on either side of the central bright spot. You then immerse these slits in a transparent liquid and illuminate them with the same light. Now you find that the first minima occur at 19.34° instead.
