Caleulate the maximum possible change in energy (AE) for a transition in the Balmer series Determine the range of wavelengths in the Lyman series. (hint: what is the lowest possible wavelength? What is the highest possible wavelength?) For a wavelength of 2166 nm, determine the assignment, both nigh and now, for the associated transition. (Hint: determine the range for each now Until you find the range that contains 2166nm)

Problem 1: Two reversible refrigeration cycles are arranged in series. The first cycle receives energy by heat transfer from a cold reservoir at temperature Tc and rejects energy by heat transfer to a reservoir at an intermediate temperature T greater than Te. The second cycle receives energy by heat transfer from the reservoir at temperature T and rejects energy by heat transfer to a higher-temperature reservoir at TH. Obtain an expression for the coefficient of performance of a single reversible...
