Using Bohr's postulates, derive the expression for the frequency of radiation emitted when an electron in a hydrogen atom undergoes transition from a higher energy state (quantum number ni) to a lower state, (nf). When an electron in a hydrogen atom jumps from energy state ni=4 to nf=3,2,1, identify the spectral series to which the emission lines belong.

1.	Using Bohr's postulates, derive the expression for the frequency of radiation emitted when an electron in a hydrogen atom undergoes transition from a higher energy state (quantum number ni) to a lower state, (nf). When an electron in a hydrogen atom jumps from energy state ni=4 to nf=3,2,1, identify the spectral series to which the emission lines belong.
Answer» Using Bohr's postulates, derive the expression for the frequency of radiation emitted when an electron in a hydrogen atom undergoes transition from a higher energy state (quantum number $n_{i}$ ) to a lower state, $(n_{f})$ . When an electron in a hydrogen atom jumps from energy state $n_{i} = 4$ to $n_{f} = 3, 2, 1,$ identify the spectral series to which the emission lines belong.

A horizontal curve with superelevation e = 0.05 (note, e=tanβ ) has a posted speed limit of 60 km/h. For this speed limit, only those vehicles with Y/X ratio(in figure) greater than 2 and travelling at speeds greater than 1.2 times the speed limit, will overturn. However, with recent increase in truck traffic the speed limit needs to be modified such that only those vehicles with Y/X ratio greater than 3 and travelling at more than 1.2 times the speed limit will overturn. What should be the new speed limit?(in km/hr round off to integer) (with respect to the figure, assume that the vehicle is travelling into the plane of the paper).50
