What is Entropy?
The entropy of a substance is a real quantity, just like pressure, volume and temperature. Its unit is joule/Kelvin (J/K).
What is Crystal structure
A crystal is a solid whose constituent atoms, ions or molecules are closely packed in a regular fashion with repeating pattern in three dimensions.
What is the Origin of Nanotechnology?
Nanotechnology is dealing with the characterization, design, production and various applications of nanostructures and nanosystems.
What are applications of Nanotechnology?
Nanotechnology have considered as the solution to our smallest to biggest problems. Applications of Nanotechnology are countless.
What is Ampere’s circuital law?
Ampere’s circuital law is one of the general laws of magnetism. This law used to find the magnetic field due to current distribution.
What are laws of Thermodynamics?
Thermodynamics is the branch of physics which deals with heat and other forms of energy and also gives relationships between them.
What is Free Electron Theory?
Drude and Lorentz gave classical free electron theory of metals theory in 1900. Another name for this is Drude –Lorentz theory of metals.
What is Faraday’s law?
Faraday’s law gives the idea about how an electromotive force comes into action when a magnetic field interacts with an electric circuit.
What is Entropy?
The entropy of a substance is a real quantity, just like pressure, volume and temperature. Its unit is joule/Kelvin (J/K).
What is Ruby Laser?
In 1960, Maiman constructed the Ruby laser. It is a three-level solid-state laser and is emitting red light of wavelength 694.3 nm.
What is the Meissner Effect?
Walter Meissner and Robert Ochsenfeld discovered a magnetic phenomenon in 1933. He studied and give the Meissner effect.
What is Helium-Neon Laser?
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.
What are Matter waves?
According to the De-Broglie concept, with each moving particle a wave is associated.
What is the Raman Effect?
The phenomenon of Raman scattering of light was experimentally observed in 1928 by Raman and Krishnan.
What are applications of Nanotechnology?
Nanotechnology have considered as the solution to our smallest to biggest problems. Applications of Nanotechnology are countless.
What is CRO or Cathode Ray Oscilloscope?
CRO or Cathode Ray Oscilloscope displays and measures the electrical signals, time intervals and phase shift between two electrical signals.
What is Diffraction? Definition and its types and comparison?
Diffraction can be defined as bending of light when it passes around the edge of an object.
