Suppose a photon travels through an interferometer with 2(L2−L1)= 327 nm. In arm 1, we place a horizontal polarizer, while in arm 2 we place a polarizer at 45 degrees. The wavelength of the laser is 500 nm.
Keep in mind: After traveling through a 45 degree polarizer, the photon will be represented by the wave function eikx2√(Ψh+Ψv).
After traveling through a horizonal polarizer the photon is represented by the wave function eikxΨh. To simplify this problem, we will ask the probability that a photon at the detector is horizontal or vertical. So the probability of observing a photon of any polarization will be normalized to one; that is, P(h)+P(v)=1. 1)
Suppose we block arm 1. What is the probability that a photon we observe at a detector is horizontally polarized? .5 2) Now we open arm 1 so that the sides can interfere. What's the probability that a photon observed at a detector is horizontally polarized? .582 3) We keep arm 1 open so that the sides can interfere.
What's the probability that a photon observed at a detector is vertically polarized?

Na food processing facility, a spherical container of inner radius r1 5 40 cm, outer radius r2 5 41 cm, and ther- mal conductivity k 5 1.5 w/m · k is used to store hot water and to keep it at 100°c at all times. to accomplish this, the outer surface of the container is wrapped with a 800-w electric strip heater and then insulated. the temperature of the inner surface of the container is observed to be nearly 120°c at all times. as- suming 10 percent of the heat generated in the heater is lost through the insulation, (a) express the differential equation and the boundary conditions for steady one-dimensional heat conduction through the container, (b) obtain a relation for the variation of temperature in the container material by solving the differential equation, and (c) evaluate the outer surface tempera- ture of the container. also determine how much water at 100°c this tank can supply steadily if the cold water enters at 20°c.

On a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 3.00 m/s.(a) what are the magnitude and direction of the velocity of the red glider after the collision? (b) is this collision elastic?
