Show the conditions for total internal reflection to happen. Arrive at the relation between refractive index and critical angle. What do you mean by optical fibre? on what rules does it work?
Coupling factor: If all the flux of a primary coil links with all the turns of a secondary then 100% coupling exists. Sometimes it is more convenient to use a coupling factor
What is the meaning of Polarization? Polarization is a quality that is only exhibited by transverse waves. For light waves, the polarization identifies the direction of vibrati
Gauss' law for magnetic fields (K.F. Gauss) The magnetic flux by a closed surface is zero; no magnetic charges present; in differential form, div B = 0.
Advantages of fibre optics: Fibre-optic communications systems have a large bandwidth, e.g. 1 GHz. The bandwidth is the maximum rate at which information can be transmitted.
