In this problem, we know that the energy in the quantum mechanics is started from the planck's law and here n is quantum number, which is known as principal quantum number.
00:31
And here n takes value as 1, 2, 3, 4, dot, dot, dot.
00:36
So it is a quantized feature.
00:38
So energy levels are quantized and the subsynth, we have subsynth which is s, p, d, f, g, h, which depends upon the value of l, which is angular momentum.
01:03
So for the n is equal to, suppose that 1, l takes value from minus n to plus n...
