  1.the positive x direction
  2.the positive y direction
  3.the positive z direction
  4.the negative z direction
  5.the negative y direction

   (a) gamma rays
   (b) microwaves
   (c) radio waves
   (d) visible light
   (e) x-rays


  1.c > b > d > e > a
  2.b > c > e > b > a
  3.a > e > d > b > c
  4.e = a = c = d = b
