Latest physics information, tutorials, concepts, interview questions, and everything related to physics.
Faraday’s law gives the idea about how an electromotive force comes into action when a magnetic field interacts with an electric circuit.
In 1895, German physicist Wilhelm Roentgen discovered X-rays. X-rays are electromagnetic in nature and application of X-rays are innumerable.
W. L. Bragg gave a simple explanation for the study of crystal structure by using the phenomenon of diffraction and name it is as Bragg’s law.
Bravais lattice gives information of the periodic array in which the repeated units of the crystal are arranged.
Shock waves are strong pressure waves in any elastic medium like water, solid or air. Supersonic aircraft or lightning produce Shock waves.
Helium-Neon Laser laser is a gas laser. In this a mixture of helium and neon gas is used as a gain medium. It was the first continuous-wave laser.
CRO or Cathode Ray Oscilloscope displays and measures the electrical signals, time intervals and phase shift between two electrical signals.
Pumping is the process to achieve population inversion .
Maxwell’s equations explain the unique co-occurrence of the electric field and the magnetic field.
Drude and Lorentz gave classical free electron theory of metals theory in 1900. Another name for this is Drude –Lorentz theory of metals.
Ampere’s circuital law is one of the general laws of magnetism. This law used to find the magnetic field due to current distribution.
LASER stands for “Light Amplification by Stimulated Emission of Radiation”.
First posulate of Special theory of relativity is "The laws of physics take the same form in all inertial frames".
Simple Harmonic Motion (SHM) is when the restoring force is directly proportional to the displacement of the body from its mean position.
Heisenberg’s uncertainty principle states that: If the x-component of the momentum of a particle is measured with an uncertainty ∆px, then its x-position cannot, at the same time, be measured more accurately than ∆x = ℏ/(2∆px).
According to the De-Broglie concept, with each moving particle a wave is associated.
Thermodynamics is the branch of physics which deals with heat and other forms of energy and also gives relationships between them.
