The diagram below shows two paths that incoming white
light might follow when striking the surface of water with a thin
film of soap over it. Which of the following must be true
concerning the distance traveled by red light within the soap film
so that upon emerging along path B it destructively interferes
with red light that reflected off the soap along path A?
a) The distance travelled within the soap = 1 wavelength of red light
b) The distance travelled within the soap = 1/2 wavelength of red light
c) The distance travelled within the soap = 2 wavelength of red light
d) The distance travelled within the soap = 2 wavelength of blue light

The space between two 15-in.-long concentric cylinders is filled with glycerin (viscosity = 8.5 × 10-3 lb·s/ft2). the inner cylinder has a radius of 1 in. and the gap width between cylinders is 0.1 in. determine (a) the torque and (b) the power required to rotate the inner cylinder at 180 rev/min. the outer cylinder is fixed. assume the velocity distribution in the gap to be linear.
