Light and quantized energy
Question | Answer |
---|---|
Electromagnetic Radiation | a form of energy that exibits wavelike behavior as it travels through space |
Wavelength | the shortest distance between equivilant points on a continuous wave |
Frequency | the number of waves that pass a given point per second |
Amplitude | the wave's height from the orgin to the crest, or from the orgin to a trough |
Electromagnetic Spectrum | encompasses all forms of electromatic radiation, with only differences in the types of radiation being their frequencies and wavelengths |
Quantum | the minimum amount of energy that can be lost or gained by an atom |
Planck's Constant | 6.626 x 10^-34 J x s |
Photoelectric Effect | frequency of light shines on a metals's surface. |
Photon | a particle of electromagnetic radiation with no mass that carries a quantum of energy |
Atomic Emission Spectrum | set of atomically emitted frequencies from the electromagnetic waves |
