Effect of Magnetic Field: Meissner Effect Explanation
Meissner Effect Experiment | Meissner Effect Explanation: When superconducting materials reach their critical temperature two exciting properties appear. Firstly, the electrical resistance of the material drops rapidly to zero and…
Introduction of Superconductivity | Superconductor Definition for Engineering
What is a Superconductor? Superconductors are materials that conduct electricity with no resistance. This means a superconductor can carry a current indefinitely without losing any energy, unlike the more familiar…
What is LASER for BTech 1st Year Physics
LASER: It is an acronym for Light Amplification By Stimulated Emission Of Radiation. It is a process by which we get a coherent, highly monochromatic and perfectly parallel beam of…
Applications of Holography For BTech Engineering Physics
Applications of Holography For BTech Engineering Physics: Holography is not only used to make three-dimensional pictures and it does not confine itself to the visible spectrum. Microwaves are used to…
Construction and Reconstruction Of Image On Hologram For Engineering Physics
Construction and Reconstruction Of Image On Hologram: Holography is a technique that enables a light field, which is generally the product of a light source scattered off objects, to be…
Basic Principle of Holography For Engineering Physics
Basic Principle of Holography: Holography is based on the principle of interference. A hologram captures the interference pattern between two or more beams of coherent light (i.e. laser light). One…
What is Holography For Engineering Physics
What is Holography For Engineering Physics: Holography is “lensless photography” in which an image is captured not as an image focused on film, but as an interference pattern at the…
Single and Multi-Mode Fibers for Engineering Physics
Single Mode Fiber Optic Cable: Single Mode fiber optic cable has a small diametral core that allows only one mode of light to propagate. Because of this, the number of…
Definition of Numerical Aperture for BTech 1st Year Physics
Definition of Numerical Aperture for BTech 1st Year Physics: sine of the maximum angle of an incident beam of some optical device, or the sine of the acceptance angle of…
