In Fig 35 31a A Beam Of Light In Material 1 Is Incident On A Boundary At An Angl

In Fig. 35-31a, a beam of light in material 1 is incident on aboundary at an angle of 30°. The extent to which the light is bentdue to refraction depends, in part, on the index of refraction n2 ofmaterial 2. Figure 35-31b gives the angle of refraction u2 versus n2for a range of possible n2 values, from na 1.30 to nb 1.90.Whatis the speed of light in material 1?
