Answer:
Photon is absorbed by the atom
Explanation:
For an electron to jump from lower energy level to higher energy level it needs some energy. This process can only take place when the atom absorbs energy, which can be in the form of photons. When the electron jumps to higher energy levels, it is known as excited state and it is not stable. So the electron will try to come back to lower energy level and in that process it will release energy.
