Ok ihve got the previous one ...
Can u help me out in calculating the Phase Shift through a thin lens of focal length f.
where d is the lens diameter. and h is the distance from the optical axis.
solution is like this.
P(h) = K/2f [ (d/2)² - h²].

Are you required to come up with your initial differential equation, or is that given to you?
"In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..."
