Vedclass · Answer

(B) An emission line is a spectral line that is formed when an electron in an atom or molecule transitions from a higher energy state $(E_2)$ to a lower energy state $(E_1)$.During this transition,the excess energy is released in the form of a photon.The energy of the emitted photon is given by the equation: $E = E_2 - E_1 = h
u$,where $h$ is Planck's constant and $
u$ is the frequency of the emitted radiation.This results in a bright line at a specific wavelength in the emission spectrum.
