1.

of the following transitions in the hydrogen atom, the one which gives an emission line of the highest frequency?

Answer»

n = 3 to n = 10
n = 10 to n = 3
n = 1 to n = 2
n = 2 to n = 1

Solution :Radiation are absorbed in option (A) and (C) and the energy of emitted radiation `E prop (1)/("Difference of orbit")`and as the difference between orbit n = 10 to n = 3 increases energy will be less, when the difference between orbits n = 2 to n = 1 DECREASES the energy emitted will be large and energy FREQUENCY in n = 2 to n = 1, highest frequency will be emitted.
