What is meant by the rest mass energy of an electron?
According to the Einstein's Theory of Relativity, the mass of a body (say a particle) occurs on the energy and on the momentum (velocity) with which the particle moves. So, we have a problem: is there a mass value that each observer can relate to? Yes: is the rest mass, that is the mass you could calculate in a frame of reference co-moving with the particle (in which the particle is still), that is the center-of-mass frame and that agree with the minimum value measurable for each observers.
Simple Microscope: A simple microscope of magnifying glass is a convex lens which form virtual erect and magnifying image of an object which is placed with in it's focal length
What are the applications of laser transitions? Applications of laser transitions: a. High coherence of light is helpful for measuring length precisely by interferometry or
When two objects collide like there velocities are not in the line of action of contact force then the collision is known as oblique collision. We can split also oblique collisi
calculate the magnifying power of a simple microscope whose focal length is 6 cm and the distance of distinct vision of 25 cm
As an electron passes close to the positive nucleus of atom, the electron is moved from its path as given in diagram. This results in deceleration of the electron. The loss in powe
