1.	In the infrared region of the atomic spectrum of hydrogen, a line is obtained at 3802 cm^(-1). Calculate the energy of this photon (h = 6.626 xx 10^(-34) J sec)
Answer» Solution :`bar(v) = 3802 cm^(-1), E = HV = h (C)/(lamda) = hc bar(v) = (6.626 xx 10^(-34) JS) (3 xx 10^(10) cm s^(-1)) xx (3802cm^(-1)) = 7.56 xx 10^(-20) J`
