n = 3, $$l$$ = 1 and m = $$-$$ 1

The value of Planck's constant is 6.63 $$ \times $$ 10^$$-$$34 J s. The speed of light is 3 $$ \times $$ 10¹⁷ mm s^$$-$$1. Which value is closest to the wavelength in nanometer of a quantum of light with frequency of 6 $$ \times $$ 10¹⁵ s^$$-$$1 ?

The orbital angular momentum of a p-electron is given as

Maximum number of electrons in a subshell with $$l$$ = 3 and n = 4 is
