In searching the bottom of a pool at night, a watchman shines a narrow beam of light from his flashlight

In searching the bottom of a pool at night, a watchman shines a narrow beam of light from his flashlight, 1.3 m above the water level, onto the surface of the water at a point d = 2.6 m from his foot at the edge of the pool (Figure 1).

Part A

Where does the spot of light hit the bottom of the h = 2.1-m-deep pool? Measure from the bottom of the wall beneath his foot. Express your answer to two significant figures and include the appropriate units.

Consider Fraunhofer diffraction of coherent light (e.g., a laser beam) from a double slit. Use Matlab (or some other program) to calculate and plot the diffraction pattern you would expect from two slits, each 0.230 mm wide, with a center-to-center separation of 0.853 mm, on a screen that is 62.3 cm downstream of the slit, when illuminated by a helium-neon laser (??=633 nm). Turn in a printout of your plot – which should have properly labeled axes, etc., of course!
