Supporting physical concept help students to understand physics topics.
Planck's Constant Viva Questions: Planck's Constant using LED [determination of Planck's constant by using light-emitting diodes (LEDs)] APPARATUS: Planck’s constant kit, wires, graph paper, and 3-4 LEDs. FORMULA USED: Planck’s constant…
Semiconductor Diode Characteristics To determine the V-I Characteristics of a p n junction diode To draw the characteristics means behavior of current in forward and reverse bias of a semiconductor junction…
Atomic Physics |Anomalous Zeeman effect In atomic physics, we observe the interaction of the magnetic field with a magnetic dipole moment. Its interpretation is complex when S'≠0. The Lorentz classical…
In this table, basic physical quantities that are used in magnetic materials are included. The symbol and conversion from one magnetic unit to the other. This conversion will be helpful…
Zeeman Effect Introduction Zeeman Effect was observed In 1896, by the Zeeman (the Dutch physicist Pieter Zeeman) that, when an atom is placed in an external magnetic field, and then…
I start it with a simple example of a classroom. As you know, in the classroom when there is no teacher students sit in random directions. While the teacher enters…
Single-mode step-index fiber: Core diameter: 7 to 11 μm Cladding diameter: generally 125 μm Coating diameter: 200 to 300 μm Numerical aperture: 0.08 to 0.15 Performance: 2 to 5 dB/km with a…
Signal attenuation within the optical fibers is usually expressed in the logarithmic unit of the decibel. Decibel is defined by the input and output power ratio of the signal for…
Ray Theory Transmission Let's see what happens when a light ray encounters a boundary separating two different media? In the figure given below, n1 and n2 are the refractive indices…
Some of the questions that arise about the optical fibers (OF) are: What is the structure of an optical fiber? How does light propagate along a fiber? What materials are…
