Thanks for the reply .. got the idea.

Let an electron is orbiting in a orbit with the principal quantum number n =1. According to wave mechanics its angular momentum is √ l(l+1) h/2∏ and angle : cosθ = ml/ √ l(l+1) How one can explain the electron angular momentum and its possible orientations for l =0? Off course for n =2, l...

Sorry I don't have the diagram. The question asked me over the phone by a teenager - I replied as said by rcgldr in previous post here. But not satisfied really.

A ring on curved path (say on bent rod) will move longer distance than the one moves on straight line in same interval of time (the two rings are released simultaneously - one moves on curved path and other one moves horizontally) - How to explain? by which principle one can explain?

Foe many years We studied that mass vary as the particle velocity approaches the velocity of light. However, recently I read that that concept of variation of mass is not correct. Mass is absolute. What changes is the momentum. Hence writing that well known equation for variation of mass is not...
