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

air crystal A B Consider 2 rays of light inside of a clear crystal. Both rays are incident upon the crystal/air boundary at the same point with the angles indicated, and ray A is internally reflected. Here, take a = B = 30 degrees. Choose all of the following statements that are true: Select one or more: O a. In order that the ray A is internally reflected, the index of refraction has to be anything greater than 2 O b. The speed of the rays in the crystal is a bit slower than the speed of light c. The speed of the rays in the crystal is a bit faster than the speed of light Od. 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 light f. In order that the ray A is internally reflected, the index of refraction has to be anything greater than 1.15 B.
