Wavelength | The distance between two consecutive peaks or troughs in a wave |
Frequency | The number of waves (cycles) per second that pass a given point in space |
Photon | A particle of electromagnetic radiation |
Excited State | Energy has been absorbed |
Ground State | Least amount of energy possible |
Quantized Energy Levels | Only certain values of atoms are allowed |
Bohr Model | Electrons must orbit like planets |
