Emission spectrum results from the movement of an electron from a higher to a lower energy level. The frequency of the photon is 5.5 * 10^14 Hz.
From the formula;
E = hc/λ
h = Plank's constant = Js
c = speed of light=
λ = wavelength = m
E =
E = J
Also;
E =hf
Where;
h = Planks's constant
f = frequency of photon
f = E/h
f =
f = Hz
