aircrystalConsider 2 rays of light inside of a clear crystal. Both rays are incidentupon the crystal/air boundary at the same point with the anglesindicated, and ray A is internally reflected. Here, take a = B= 30degrees. Choose all of the following statements that are true:Select one or more:a. In order that the ray A is internally reflected, the index of refraction has to be anythinggreater than 29 b. The speed of the rays in the crystal is a bit slower than the speed of lightO c. The speed of the rays in the crystal is a bit faster than the speed of lightO d. Since A is internally reflected, B also must be internally reflected.e. The speed of the rays in the crystal is equal to the speed of lightf. In order that the ray A is internally reflected, the index of refraction has to be anythinggreater than 1.15

If so, describe it. O Doubling the angle of incidence approximately halves the angle of refraction. O Doubling the angle of incidence approximately doubles the angle of refraction. O Doubling the angle of incidence approximately quadruples the angle of refraction. There is no trend in the resulting values. Based on your observations, what would you predict the angle of refraction to be for an angle of incidence of 40°? How does your value compare with that inferred from the figure? () ssed u asuy
