When an electron of an atom returns from an excited state to the ground state, it emits energy in the form of a photon. How does the change in energy level compare to the energy of the emitted photon?

The photon possesses energy in the form of an electromagnetic wave of some frequency and wavelength (where frequency * wavelength = speed of light).
The change in energy level (E) of the excited state and ground state is given by the formula,
E=hf (or) E = hc/λ
Where,
h = Planck’s constant (6.626*10 -34Js)
f = Frequency of the photon
c = speed of light
λ = Wavelength of the photon
