Abeam of light of two different wavelengths enters a pane of glass 3.2 mm thick at an angle of incidence of 59°. the indices of refraction for the two different colors are 1.5 and 1.53. because of dispersion, the colored beams, although parallel, are separated by a small distance. how far apart are they? (give your answer to the nearest 0.0001 mm)

Acommercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at -35°c by rejecting waste heat to cooling water that enters the condenser at 18°c at a rate of 0.25 kg/s and leaves at 26°c. the refrigerant enters the condenser at 1.2 mpa and 50°c. if the compressor consumes 3.3 kw of power, determine (a) the mass flow rate of the refrigerant, (b) the refrigeration load, (c) the cop, and (d) the minimum power input to the compressor for the same refrigeration load.
