A screen 1-m wide is 2.0 m from a pair of slits illuminated by 633-nm laser light, with the screen's center on the center line of the slits. If the slit spacing is 0.10 mm, find
a) The highest order bright fringe visible on the screen?
b) How many fringes will be visible on the screen?
c) How many bright fringes would be visible on an infinitely wide screen?
You may also assume that v_0 gg sqrt{2gL}, so that the change in hammer's gravitational potential energy, as it drives the nail into the block, is insignificant.
