The existence of quantized energy levels in an atom can be inferred from

This concept is inferred from quantum mechanics. According to quantum mechanics, electrons can absorb or emit energy by a discrete amount of energy called quanta. This follows from the two of contradict the theory of the wave-particle theory of light. It was widely accepted already that the light behaves as a wave. However, questions remain unanswered about why the electromagnetic waves that emit or absorb light at specific frequencies. Until Planck proposed his equation: E = hv, where E is the energy, h is called Planck's constant and ν is the frequency.In this equation, means that increases the energy is progressing in discrete amounts of frequencies, and this constant is denoted by h.
