Quantumphysics
Our view of atoms has changed because of Quantum Physics. In the past, an atom was portrayed as a nucleus orbited by electrons. Modern quantum physics describes the probability of the location of an electron in a time frame. Electrons can jump from one orbital to another as they gain or lose energy, but they cannot be found between orbitals.
Wave-Particle Duality
This principle is the result of experiments showing that light can have the properties of particles or waves depending on how it was measured. Today we know that these forms of energy are neither particles nor wave but instead distinct quantum objects.
Superposition
The Term "Superposition" describes when an object has multiple states at the same time. An object in superposition can be represented by an equation with more than one solution.
Uncertatity Principle
With a quantum object, we can not know the precise position and velocity simultaneously. If we know the exact position of an electron, we do not know its precise speed.
Entanglement
Entanglement occurs when two or more objects are connected to each other so that they can be thought of as existing in a single system, even though their position might be far apart. These objects can only be fully described by knowing the other object. But this means aslo that learning information about one object automatically tells you information about the other object.
The Double Slit Experiment
Perhaps the most definitive experiment in the field of quantum physics is the double-slit experiment. This experiment, which involves shooting particles such as photons or electrons though a barrier with two slits, was originally used in 1801 to show that light is made up of waves. Since then, numerous incarnations of the experiment have been used to demonstrate that matter can also behave like a wave and to demonstrate the principles of superposition, entanglement, and the observer effect.
