| Question | Answer |
|---|---|
| electronmagnetic radiation | a form of energy that exhibits wavelike behavior as it traver through space |
| wavelength | the shortest distance between equivalent points on a continuous wave |
| frequency | the number of waves that pass a given point for a second |
| amplitude | a wave heights from the orgin to a crest or from theorigin to a tough |
| electromagnetic spectrum | encompasses all forms of electronmagnetic raditon |
| quantum | the minimum amount of energy that can be grand or lost by an atom |
| Planck's constant | has a value of [6.626x10^-34Jxs] |
| photoelectric effect | are emitted from a metal's surface when light of a certain frequency shines on a surface |
| photon | a particle of electronmagnetic radiation with no mass that carries a quantum of energy |
| atomic emission spectrum | an element is the set of frequencies of the electromagnetic waves emitted by atoms of the element |
| ground state | the lowest allowable energy state of an atom |
