Do fibers have losses?
Everything in the universe is inefficient. It means that while a measured amount of something enters in a system, less comes out than initially went in. When you pour a liter of water in one end of a pipe, then you will always find less than a liter out of the other end. When you apply a voltage to the extreme of one wire, it doesn't matter how you do this, you will find a lesser value at the other end.
Fiber optics are no exception that the light entering one end encounters all types of obstacles and flaws, which are resulting in losses; from 2 to 10 percent for every running meter.
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
A moving elevator and a ball or an object being dropped inside it with some given speed/acceleration. Ans) You must know the concept of inertial and noninertial frames.non inertia
Magnetism - Basic concepts: 1. Pole strength: The ability of a pole of a magnet to attract or repel another magnetic pole is called its pole strength. Units : A-m 2.
Obtain Relativistic expression for the kinetic energy of the particle.
My question is that if voltage is increased, the electrons will move faster and the distance between them is changed. Why?
