An EM wave is normally incident on a boundary between two materials (n1≪n2). If the incident wave starts in material 2,
most of the wave is reflected back; very little of the wave transmits through material 1
some of the wave is reflected back; some of the wave transmits through material 1
very little of the wave is reflected back; most of the wave transmits through material 1
