Before study the properties of photon we must have to know some basic introduction of photon. In 1905, Einstein explained photoelectric effect by considering light consisted of quantum of energy …
How to Reduce Spherical Aberration The following 5 methods are usually used to reduce the spherical aberration. By Stop Method. By using plano-convex lenses. By using two convergent lenses separated …
Aberration in Optics In the simple theory of image formation by lenses, it is assumed that an object is situated very close to the principal axis and each point object …
Suppose we have two lenses of focal lengths f1 and f2 separated by a distance x as shown in fig below. L1, L2 correspond to the position of two lenses …
The matrix Tm is called Translation Matrix. The matrices can be used to find the position of the final image. The method of writing linear equations for the coordinates of …
What is fermat’s principle? This principle states that the light always travels that path in a medium from one point to another point which takes the minimum (i.e least) time. …
The branch of physics which deals with the study of optical phenomenon like reflection, refraction, dispersion, interference, diffraction, polarization etc. is known as optics. Optics is classified into two categories: …
In this article we are going to study Current Gain in Transistor of Common Base Transistor and Common Emitter Transistor. Along with the formula of current gain in transistor. Current …
Semiconductor are classified into two classes: Intrinsic (or pure) semiconductors Extrinsic (or impure) semiconductors Intrinsic Semiconductors A semiconductor in an extremely pure form is known as intrinsic semiconductor. A semiconductor …
