When an electron in excited energy level drops to a lower energy

level, a photon is emitted.

If the electron is dropping to n=1, which transition will emit the longest

wavelength? n= ____ was to n=1.

The transition between n=1 and n=2 corresponds to the longest wavelength with the lowest frequency.

An electron is said to be "excited" when it is promoted to a higher energy level inside its bound state.

Either the electron absorbs a photon and obtains all of its energy, or it receives energy via a collision with another, energetic electron.

Understanding energy levels :

Therefore the transition between n=1 and n=2 corresponds to the longest wavelength at the lowest frequency.

The higher the frequency of a photon, the higher its energy.

The longer the wavelength of a photon, the lower its energy.

                                  E ∝ 1/λ      [ FOR PHOTON ]

The lowest energy is 1 eV, which corresponds to the transition between the n=1 and n=2 levels.

The longest wavelengths are associated with the lowest energies, so transitions between n=1 correspond to the longest wavelengths.

The term "thermal excitation" refers to the process by which electrons within a semiconductor crystal lattice are elevated to a higher energy band via lattice vibrations. This process, known as electron relaxation, occurs when an excited electron returns to a less energetic state.

As a result, a photon is released into the environment, or energy is transferred to another particle. The amount of energy released is proportional to the gap in potential energy between the electron's lowest and highest states.
