Question

PLEASE ANSWER ACCURATELY AS POSSIBLE! THIS IS A TAKE HOME TEST! EXPLANATION HAS TO BE IN DEPTH! THANKS!

9) (a) Shown below is a rectangular prism made of two clear plastics whose indices of refraction are n, and n. The prism is immersed in a liquid whose index is n, (n<n<n). A ray of light is shown incident on one face of the prism at a 32 angle. Also shown are four possible emerging rays from the prism. Which ray is the proper emergent ray? Explain fully. (b) For the situation shown at the right determine the field at the point P. All currents and distances between wires are the same. Show explicitly how you found this. P .

(9) using shell's law as I nsini = p sink 1 as D psinh, = rsinha (10) o at lll r sind = nsindz tilij from eq. (6 (1) and (n) nsini= n sinds sini= sink Hence final emerging say must be parallel to the incident ray. Therefore 4th say from left to right which is parallel to 1st ray (incident) is possible emergent say
