(11.3) At points where the difference in path length iso, λ·2 , the screen is (11.4) Suppose a Young two slit experiment is totally immersed in water. How does the pattern of maxima and minima change compared to the usual Young experiment conducted in air? (a) the pattern of maxima and minima stays the same. (b) for the experiment in water the maxima and minima occur at smaller angles (c) for the experiment in water the maxima and minima occur at larger angles. 12.
