That has nothing to do with why coloured light creates "new" colours when you look at two overlapping beams of different-coloured light. For other wavelengths, however coherence plays a big part in why this is not feasible (Wikipedia has good articles on coherence length, for example). With...

Hi bjacoby, Thanks for the reply. After posting this I accidentally came across a copy of that book in the library, and I worked out the inductances as follows: First, the self inductance of a single coil, square cross section, can be calculated from a table or formula given. Then, the...

Hi all, The situation is this: I need to calculate the self inductance of two solenoids wired in series, of equal radius and a given separation d. They are coaxial. The length h of each is known. Most double-solenoid references I found looked at the mutual inductance, and not the...
