|
Electromagnetic spectrum
|
The range of all possible frequencies of electromagnetic radiation.
|
From the lowest modern radio communication to gamma radiation
|
|
|
Radiant energy
|
The energy of electromagnetic radiation.
|
Calculated by integrating radiant flux(power). Radiant may be visible or invisible to the human eye.
|
|
|
Probability( math definition)
|
A type of ratio where we compare how many times an outcome can occur compared to all possible outcomes.
|
Answer for the question:" How certain are we that the event will occur? "
|
|
|
Electron cloud
|
A phenomenon that occurs in particle accelerators and reduces the quality of the particle beam.
|
Created when accelerated charged particles disturb stray electrons already floating in the tube.
|
|
|
Emission spectrum
|
A chemical compound is the spectrum of frequencies of electromagnetic radiation emitted due to an atom or molecule making a transition from a high energy state to a lower energy state.
|
Can be used in chemical analysis of substances.
|
|
|
Quantum mechanics
|
Physical phenomena at nanoscopic scales where the action is the order of the Planck constant
|
It departs from classical mechanics primarily at the quantum realm of atomic interactions of energy and matter.
|
|
|
Classical( Newtonian) mechanics
|
The set of physical laws describing the motion of bodies under the action of a system of forces
|
One of the oldest and largest subjects in science, engineering and technology.
|
|
|
Lewis electron dot diagrams
|
Diagram that show the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.
|
Show each atom and its position in the structure of the molecule using its chemical symbol.
|
|
|
Momentum
|
The product of the mass and velocity of an object.
|
P=mv
|
|
|
Wave-particle duality of nature
|
The concept that every elementary particle or quantum entity exhibits the properties of not only particles, but also waves.
|
It addresses the inability of the classical concepts "particle" or "wave" to fully describe the behavior of quantum-scale objects.
