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.
Electric Current: Electric current may be described as the rate of flow of charge. I=q/T Where, I = electric current q = charge T = time The unit of current i
There are mainly three parts of Logic gates (1) The 'OR' gate (i) It has two inputs (A and B) and only one output (Y) (ii) Boolean expression is Y = A + B (iii
A parallel plate capacitor is made from 25 plates, each 70mmby 120mm interleaved with mica of relative permittivity 5. If the capacitance of the capacitor is 3000pF verify the

Is CPH a quantum energy unchangeable? Answer- Yes, the quantum energy (photon) is made of lots CPH, different between photons depend to the number of CPH that they are made of.
Q. In Young's double slit experiment the distance between the slits is 1.9 mm. The distance between the slit and the screen is 1 m. If the bandwidth is 0.35 mm Compute the waveleng
A glass sphere of radius 15 cm has a small air bubble at a distance of 6 cm from its centre. When viewed normally along its diameter from the nearest side, the bubble seems to be 7
