### Groups of Spectral Lines

Professor Lavelle mentioned that UV light is when a high energy e- drops to the n=1 state, visible light is for the n=2 state, and infrared is for the n=3 state. How does this apply to gamma rays, x-rays, microwaves, and radio waves?

### Re: Groups of Spectral Lines

The type of light that is emitted depends on how much energy is lost when the electron drops from a higher to a lower energy state. Gamma rays and x-rays are even higher energy waves than UV, so would require much higher level electrons to be emitted than UV does. Microwaves and radiowaves are very low energy waves, so would be generated by small drops in energy level.
