An EM wave is normally incident on a boundary between two materials (n1n2). If the incident wave starts in material 2,

  1. most of the wave is reflected back; very little of the wave transmits through material 1
  2. some of the wave is reflected back; some of the wave transmits through material 1
  3. very little of the wave is reflected back; most of the wave transmits through material 1
  4. ???
