Schrödinger Equation
The Schrödinger equation is a foundational equation in quantum mechanics that describes the evolution of quantum states over time. It was formulated by Erwin Schrödinger in 1926 and provides a mathematical framework for understanding the wave-like behavior of particles at the quantum level. The equation plays a crucial role in determining the behavior and properties…

Phosphorescence
Phosphorescence is a type of photoluminescence in which a substance emits light after being exposed to light energy (electromagnetic radiation). Unlike fluorescence, which is usually short-lived, phosphorescence can continue to emit light for a period of time after the initial exposure. The excited electrons tend to decay at a much slower rate. This can be…

Fluorescence
Fluorescence is a type of photoluminescence in which a substance absorbs light at a certain wavelength and then emits light at a longer wavelength, sometimes within the visible spectrum. This phenomenon is used in a wide range of applications, including biomedical imaging, chemical analysis, and materials science. One of the primary differentiating factors between fluorescence…

Photoluminescence
Photoluminescence refers to the emission of light from a material after it has been excited by an external (photon) source, such as a laser. This process involves the absorption of a photon by the material, followed by the emission of that photon as visible light. Photoluminescence can be used to study the optical and electronic…

Newton’s Third Law
Forces come in pairs which are of the same magnitude but opposite direction. Newton’s third law of motion, also known as the law of action and reaction, is one of the fundamental principles of classical mechanics. One of the statements of the third law is that forces come in pairs. This means that if object…

Newton’s Second Law
The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Newton’s Second Law of Motion is one of the fundamental principles of physics. It states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional…

Newton’s First Law
An object at rest will remain at rest, and an object in motion will continue in motion with a constant velocity, unless acted upon by a net external force. In simpler terms, this means that objects tend to maintain their state of motion or rest until something acts on them. This law is one of…

Gravitational Potential Energy
Gravitational potential energy is a form of potential energy that an object possesses by virtue of its relative location within a gravitational field. When an object is lifted against the force of gravity, work is done on the object, and gravitational potential energy is stored in the object. Formula for Gravitational Potential Energy The formula…

Kinetic Energy
Kinetic energy is a type of energy that an object possesses due to its motion. When an object is in motion, it has the potential to do work, and kinetic energy is the energy associated with this potential. Formulas for Kinetic Energy The formula for translational kinetic energy is: where KE is the translational kinetic…
