Manufacturers of wire (and other objects of small
dimension) sometimes use a laser to continually monitor the
thickness of the product. The wire intercepts the laser beam, pro-
ducing a diffraction pattern like that of a single slit of the same
width as the wire diameter (Fig. 36-37). Suppose a helium-neon
laser, of wavelength 632.8 nm, illuminates a wire, and the diffrac-
tion pattern appears on a screen at distance L = 2.60 m. If the
desired wire diameter is 1.37 mm, what is the observed distance
between the two tenth-order minima (one on each side of the
central maximum)?

Explain.arrow_forward3) Since we are treating light as a particle, it is appropriate to consider a pool ball bouncing off the edges of a pool table as analogous to reflection of a light particle from a mirror. Consider the pool table and cue ball shown below. The table is 8' x 4' and the spacing between white marks along the outer cushion of the table is 1'. Imagine that you want to hit the cue ball in such a way as to hit the ball located near the top middle pocket. Based on the locations of the other balls, you determine that the only way to do this is to "double bank'" the ball off two sides as shown below. If estimate that you must hit the first side at a point 3 1/3 feet from the cue ball, determine the angle O which the cue ball will make as it is approaching the other ball. you 8' 1' 1' 100 C45 4' 53° Cue Ball 65° Mi 90 120° 3 1/3' dataarrow_forwardA very thin stretched soap film looks black.
