So, 44 is the value of the 1000th term of the series 1,2,2,3,3,3,4,4,4,4...
Q. How are Electromagnetic (EM) waves propagated?
Posted by: Vipuljaglan
A. If an electric or magnetic field is constant then they can be analysed independently without looking at the interactions between them. But a time varying magnetic field acts as a source of electric field (Faraday's law) and a time varying electric field acts as a source of magnetic field (Ampere's law).
So, when either an electric or magnetic field is changing with time, a field of the other kind is induced in adjacent regions of space. These electromagnetic waves propagate through space from one region to another, even when there is no medium in the intervening region.
