The frequency of the emitted light is the same as the frequency of the electron. The atom contains only a few discrete types of electrons. The arrows indicate the direction of a ray of light as it strikes each material. The medium surrounding each material is not necessarily air. A B. Material B C. Material C 7.
Electrons follow circular orbital paths much like planets orbiting the sun.
All of the electrons occupy the lowest energy level in the atom. The electron energy levels are determined by interference between the waves associated with each electron. Electrons behave like waves unless they are in the ground state. Electrons occupy orbitals that can only specify the probability of finding an electron at some point. A. infrared light B. red light C. ultraviolet light D. gamma rays E. radio waves 9.
