prism pathway of light

Click for Explanation

This question requires the examinee to trace the pathway of light through an object immersed in a fluid with a higher refractive index. Initially, the light enters the prism and speeds up, causing the light to refract away from the normal, eliminating choices A and B. As the light exits the object and reenters the fluid, the light slows down and refracts towards the normal surface. Thus, C is the correct answer.
