There are two choices of underlying material. For each, the angle of refraction 02 versus the incident angle 0, is given in Figure(b) below. The vertical axis scale is set by e15 = 86°. Without calculation, determine whether the index of refraction of (a) material 1 and(b) material 2 is greater or less than the index of water (n = 1.33).

For each, the angle of refraction 02 versus the incident angle 01 is given in Figure (b) below. The vertical axis scale is set by 01s =86°. Without calculation, determine whether the index of refraction of (a) material 1 and (b) material 2 is greater or less than the index of water (n = 1.33).
