Black Hole
Black holes are among the most mysterious and awe-inspiring objects in the universe, regions of spacetime where gravity is so strong that nothing—not even light—can escape. Born from the collapse of massive stars and predicted…
-
Interior of Black Hole
Black holes sit at the edges of both our universe and our scientific understanding. They are among the strangest objects ever predicted by physics—regions where gravity pulls so strongly that nothing, not even light, can…

Enthalpy
Enthalpy is a fundamental concept in thermodynamics, one of the most important branches of physics that deals with the relationships between heat, work, and energy in physical systems. It is a state function that helps…

What is Entropy – Entropy
Entropy stands as a cornerstone of physics, encapsulating the measure of randomness or disorder within any physical system and governing the natural direction of physical processes. At its essence, entropy reflects how energy disperses or…

Evanescent Field
The concept of the evanescent field occupies a central position in the study of wave phenomena, especially within optics, electromagnetism, and quantum mechanics. It describes a unique and fascinating behavior of electromagnetic waves at interfaces…

Evanescent Wave
An evanescent wave is a fascinating and subtle phenomenon in physics that arises when a wave encounters a boundary or an interface in such a way that it cannot propagate through the second medium in…

What is First Law of Thermodynamics – First Law of Thermodynamics
The First Law of Thermodynamics represents one of the most profound and universal statements in all of physics, asserting that energy is an indestructible quantity—it can shift forms or move between systems, but it can…

Frame of Reference
A frame of reference is one of the most fundamental concepts in physics, serving as the basis for describing and understanding motion, rest, and the laws governing the physical universe. It is the conceptual or…
