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)?

ray r, reflects once from a mirror and
a light wave along ray r, reflects twice
from that same mirror and once from
a tiny mirror at distance L from the

of the rays.) The waves have wave-
length 620 nm and are initially in phase. (a) What is the smallest value
of L that puts the final light waves exactly out of phase? (b) With the
tiny mirror initially at that value of L, how far must it be moved away
from the bigger mirror to again put the final waves out of phase?
•48 A high-powered laser beam (A = 600 nm) with a beam diam-
eter of 12 cm is aimed at the Moon, 3.8 x 10° km distant. The beam
spreads only because of diffraction. The angular location of the
edge of the central diffraction disk (see Eq. 36-12) is given by

sin 0
where d is the diameter of the beam aperture. What is the diameter

Their eyes react this way because of a thin layer of reflective tissue called the tapetum lucidum that is located directly behind the retina. This tissue reflects the light back through the retina, which increases the available light that can activate photoreceptors, and thus improve the animal’s vision in low-light conditions. If we assume the tapetum lucidum acts like a concave spherical mirror with a radius of curvature of 0.750 cm, how far in front of the tapetum lucidum would an image form of an object located 30.0 cm away?
