WebIn Figure (a), a beam of light in material 1 is incident on a boundary at an angle of θ1 = 30∘. The extent of refraction of the light into material 2 depends, in part, on the index of refraction n2 of material 2 . Figure (b) gives the angle of refraction θ2 versus n2 for a range of possible n2 values. The vertical axis scale is set by θ2a ...
