Four transparent blocks with indices of refraction n,, n2, n;, and n4 are stacked as shown. n1 45° 90° n3 n2 90° na A ray of light (r) travels through the first block and is incident on the interface between the first and second block. It is subsequently reflected and refracted (r, through ra) at interfaces between the other blocks as shown. The reflection at the interface between the second and third blocks is a case of total internal reflection. Given this situation, which of the following statements is FALSE? O The speed of light is lower in block two than in block three. O nz is larger than n O The speed of light is larger in block three than in block one. O nz is larger than n, O nz is larger than n4 O rş is a reflected ray.
