- Heisenberg’s Uncertainty Principle is one of the most outstanding results of quantum mechanics. It states that one (often, but not always) cannot know all things about a particle (as its wave function defines it) at the same time. This principle is mathematically manifested as non-commuting operators.
- In quantum mechanics, the uncertainty principle (also known as Heisenberg’s uncertainty principle) is any of a variety of mathematical inequalities asserting a fundamental limit to the accuracy with which the values for specific pairs of physical quantities of a particle, such as position, x, and momentum, p, can be predicted from initial conditions.

Harmonic motion: periodic motion consisting of one or more vibratory movements that are symmetric about a region of equilibrium, as the motion of a vibrating string of a musical instrument.
-
Amplitude—maximum displacement from an object’s equilibrium position oscillating around such an equilibrium position. Frequency—number of events per unit of time. Period: the time it takes to complete one oscillation.
- For waves, these variables have the same basic meaning.
- Amplitude: The distance between the resting position and the maximum displacement of the wave.
- Frequency: The number of waves passing by a specific point per second
- Period: The time it takes for one wave cycle to complete.
- A high-energy phase is fast; a low-energy phase is slow. In chemistry, thermodynamics, and many other related fields, phase transitions (or phase changes) are the physical processes of transition between the primary states of matter: solid, liquid, and gas. A phase of a thermodynamic system and the states of matter have uniform physical properties.
- The superposition principle, also known as superposition property, states that, for all linear systems, the net response caused by two or more stimuli is the sum of the reactions that would have been caused by each stimulation individually. The principle of superposition states that every charge in space creates an electric field at a point independent of the presence of other charges in that medium. The resultant electric field is a vector sum of the electric field due to individual charges.
- Virtual particles do not necessarily carry the same mass as the corresponding fundamental particle, although they always conserve energy and momentum. The closer its characteristics come to those of ordinary particles, the longer the virtual particle exists. In a near-vacuum, quantum effects can cause short-lived particles to appear. On average, when they disappear, no extra energy remains in the universe, so on average, the total amount of energy in the universe is conserved.
- The Lamb Shift: The interaction between vacuum energy fluctuations and the hydrogen electron in these different orbitals is the cause of the Lamb shift, as was shown after its discovery. The Lamb shift has since played a significant role through vacuum energy fluctuations in the theoretical prediction of Hawking radiation from black holes. When the Lamb shift was experimentally determined, it provided a high precision verification of theoretical calculations made with the quantum theory of electrodynamics. These calculations predicted that electrons continually exchanged photons, this being the mechanism by which the electromagnetic force acted.
- An object’s motion is to find out the distance traveled by the entity in unit time is referred to as speed. The speed of an item is described by its magnitude and is need not be constant. For non-uniform motion, the rate of movement is defined by their average speed.
