Problem Set #1 Physics 322 Optics Fall 2011 1) Express 1 1 – r 2 e –i δ with a real denomenator (r is real). 2) For the field E = E0 +iE 1 e ikr = E e i θ , what are |E| and θ = arg(E)? 3) Evaluate e ikr + e – ikr – 2 ikr at r = 0. 4) Evaluate i and arg( i ). 5) For which integers is i n real? Positive? Nonreal? 6) For z = 2 - i, what is arg(z)? arg(iz)? arg(z*)?
