The energy levels of an atom of element X are shown in the diagram. Which one of the level transitions will result in the emission of photons of wavelength 620 nm? Support your answer with mathematical calculations.
An atom has many orbits with different energy levels in which electron revolve in circular path around the nucleus, when an electron jump from higher energy level to lower energy level, it emits energy in the form of electromagnetic wave (Photon) whose wavelength is such that energy of wave emitted is equal to the energy difference between two energy levels
We know Energy of a Photon is given as
Where E is the energy of the photon in Joules
h is Planck’s Constant
h = 6.626 × 10-34 Js
C is the speed of light
C = 3 × 108 m/s
