I feel this sentence is slightly redundant. What continuity conditions are we talking about here? Are these simply, $(\bold{D}_N(x=0) - \bold{D}_P(x=0)) \bullet \bold{n} = \sigma = 0$ $\psi_N(x=0) - \psi_P(x=0) = 0 $ Also, what is the significance of having the same dielectric constant in both sides? What effect does this have on the continuity conditions? Thanks again, Andres ![Screenshot_2020-07-29_at_17.12.30](/uploads/5375c516200f630388d0bb868c70a87f/Screenshot_2020-07-29_at_17.12.30.png) Hi again, So in the highlighted section.
