Question | Answer |
---|---|
Electromagnetic radiation.... | is a form of energy that exhibits wqavelike behaviors as it travels through space. |
Wavelength... | is the shortest distance between equivalent points on a continuous wave |
Frequency... | the num of waves that pass a given point per second. |
Amplitude... | the waves height from the origin to a crest, or from the origin to a trough. |
Electromagnetic Spectrum... | radiation being their frequencies and wavelengths. |
Quantum... | the minimum amount of energy that can be gained or lost by an atom. |
Planck's Constant | a value of 6.62 6x10-34 J.s, where j is the symbol for the joule, the SI units of energy. |
Photoelectric effect... | emitted from a metal's surface when light of a certain frequency shines on the surface. |
Photon.. | is a particle of electromagnetic radiation with no mass that carries a quantum of energy. |
Atomic Emission Spectrum | of an element is the set of frequencies of the electromagnetic waves emitted by atoms |
