1/λ=ry(1/n21 -1/n22)
you set n1 = 1 and taken2 greater than 1, you generate what is knownas the lyman series.
a) find the wavelength of the first member of this series. thevalue of h is 1.05457 e -34 j*s; the rydberg constantfor hydrogen is 1.09735 e7 m-1 ; the bohr radius is5.29177 e-11 m; and the ground stae energy for hydrogen is 13.6057ev.
answer in units of nm.
b) consider the next three members of this series. thewavelengths of successive members of the lyman series approach acommon limit as n2 → [infinity]. what is thislimit?
answer in units of nm.

4r-134a enters the condenser of a residential heat pump at 800 kpa and 50°c at a rate of 0.022 kg/s and leaves at 750 kpa subcooled by 3°c. the refrigerant enters the compressor at 200 kpa superheated by 4°c determine (a) the isentropic efficiency of the compressor, (b) the rate of heat supplied to the heated room, and (c) the cop of the heat pump. also, determine (d) the cop and rate of heat supplied to the heated room if this heat pump operated on the ideal vapor-compression cycle between the pressure limits of 200 and 800 kpa.
