## Six Major Misconceptions in LASER what Student Thinks ?

Six Major Misconceptions in LASER what Student Thinks about some physical concepts? Like what is ground and excited state of the students? They just explain only about energy not reason Read more

## Derivation for Velocity Addition in Special Theory of Relativity

The velocity addition topic into the special theory of relativity is interesting one, where in addition to the two observers (two frames) included; (1) an idea of the additional object Read more

## Derivation of Relativistic Kinetic Energy and Total Energy

In classical mechanics, the mass of a moving particle is independent of its velocity. But in special theory of relativity one can see that mass is also relative. In the Read more

## Relativistic Mass in Special Theory of Relativity Part 2 Engineering Physics

In classical mechanics, mass of a particle is considered to be a constant quantity and independent of its velocity. However in relativistic mechanics the length, time and mass also depends Read more

## Relativistic Mass in Special Theory of Relativity

In classical mechanics, mass of a particle is considered to be a constant quantity and independent of its velocity. However in relativistic mechanics the length, time and mass also depends Read more

## Length Contraction | Special Theory of Relativity|

In this video lecture I have discussed about the Length Contraction. To understand it the basic information about the two transformations (Galilean and Lorentz) are important. It is based on Read more

## Galilean Transformation |Special Theory of Relativity|

The Einstein in 1905 introduce the concept of Special Theory of Relativity. In our daily life we see the effects of the relative motion, for an example if suppose there Read more

## Time Dilation |Special Theory of Relativity|

In this video lecture I have discussed about the time dilation, which comes under the Special theory of Relativity Unit. To understand this concept the basics like frame of reference, Read more
