I am just not sure how I should proceed with this question. I'vebeen playing with it for a while but can't seem to figureitout.

You are lying on the bottom of the swimming pool filled 14 ftdeepwith water. What is the diameter of the "hole" at the watersurfacethrough which you can see out of the pool?

I know that:
14 feet = 4.267 m
n water = 1.33
n air = 1
Snell's Law

How can I proceed with Snell's Law when I don't have a valueforeither angle? Or do I need another equation?

I need a step by step answer on how to solve problem 11.25 Iattached the question from the book and answers that the back ofthe book gave me but I need someone to explain how and why you getthose answers, thanks.

on part b I understand the Îs_tot=0, but how does therule Îl=+/- 1 work?

-do the states on left collum (1s², 1s2s, 1s3s) allhave l=0 and the ones on right collum (1s2p, 1s3p) all have a l=1then?

in part c What does mestastable mean, and how do you know whenit is?

-Does mestastable mean it has no where else to decay or what,and if so then why isn't 1s² mestastable, is it becauseit's not an excited level, and how do you decide which ones areexcited levels?

Okay so this is a theory question from a more advanced question.Idon't want more help on the question than answering thefollowing(because I understand the rest of it already, but I wantto clarifysomething for myself).

So You have a loop of wire, 103 turns. 10 A going through thisloop.You are told to find the magnetic field at a point that is.21 moutward on its axis (axis is perpendicular to the circle). SoIwould use:
dB=(u0)/4pi * Int((I*ds x r^)/r^2) wherer^is the unit vector for r, which, for example at the top oftheloop, would be downward and outwards towards that point ontheaxis... If this is the case, SEE MY ATTACHED DIAGRAM: Isthemagnetic field dB from that small portion at the top o theloop
, really pointing in the direction as indicated on the diagram?Ijust want to be sure I have this right
