Homework Statement
Find E1, E3, and ps2
Homework Equations
boundary conditions
The Attempt at a Solution
(these are class notes)[/B]
I understand how to find E1, but I am a bit confused about the reasoning behind finding E3... Why do we leave the 2x(hat) for E3...? I though that only tangential components of E don't change across a charge density, but the normal does change which is why we have to use boundary conditions and n (dot) (D1-D2)... But we don't have ps here so we can't use that. Why do we keep the 2x(hat)? I get the y(hat) and z(hat) part because they are tangential, but not the x(hat).
