Why are orbits also called as energy levels?

• According to Bohr's atomic theory, electrons in an atom revolve around the nucleus in their fixed path called orbits.
• These orbits are also called energy levels and each orbit have a specific energy associated with it.
• Because while revolving on this particular orbit electron have some specific amount of energy which allowed electron to remains in these orbits and so these orbits are called energy levels.
• These orbits are named as K orbit, L orbit, M orbit, N orbit and so on, where K is the first and innermost orbit having lowest energy. Energy of orbits increases in the order K < L < M < N and so on.
