## Photoelectric effect – brief introduction

Photoelectric effect The main idea of this article is to present a brief overview of the phenomenon called photoelectric effect. Photoelectric Effect is the emission of electrons by a substance under the action of light Photoelectric phenomenon was first noticed by Hertz when he noticed that sparks occur more readily in the air gap of his transmitter when ultraviolet light is directed at one of … Continue reading Photoelectric effect – brief introduction »

## heisenberg uncertainty principle

What is heisenberg uncertainty principle? Heisenberg Uncertainty Principle or indeterminacy principle was given by German scientist Warner Heisenberg according to which position and momentum of an object can not be measured simultaneously.  So if we measure the position of some particle more precisely then its momentum is measured less precisely and vice verse.Heisenberg uncertainty principle can be written as follows If a measurement of position of … Continue reading heisenberg uncertainty principle »

## Coordinate transformation : translation, inclined and rotation

This article ” Position of a particle ” is for B.Sc. students. We have also defined inertial and non inertial frame of reference in this article. Position of a particle (a) By Position Vector:- The line joining the point P and the origin ‘O’ of the frame of reference that is $\vec{PO}$ is known as position vector and is also represented by $\vec{r}$. (b) By … Continue reading Position of a particle (Mechanics) »
