Problem 3 [20 points) This problem is composed into two independent parts. Part 1 (10 points) For parts a), b) and c) of the below question, fill in the empty boxes with your answer (YOUR ANSWER MUST BE ONLY A NUMBER; DO NOT WRITE UNITS; DO NOT WRITE LETTERS). Two parallel waves travelling together are represented by the following functions: E1 E, sin(wt+al) and E2 = Eo2sin(wt + a2), with: E01 = 24 V/m, E02 = 88 V/m, w=161 rad/s, • Q1 = 0.2977 rad, Q2 =1.08 rad. a) [5 points) Find the resultant amplitude E, for the superposition of the two waves. V/m Eo = b) [4 points] The expression of the resultant wave for the superposition of E1 and E2 is of the form E= Eosin(wt + a). Find tan(a). tan(a) c) (1 point] Consider tan(a)=1.912. Deduce a. rad
