**Explanation:**
In this experiment, students are asked to determine how the refraction of light in water alters the perceived position of the fish compared to its actual position. By demonstrating the principle of apparent depth in optics, students learn about the behavior of light at the interface between two different mediums—water and air. The mirrored bottom adds complexity by reflecting the image of the fish, requiring comprehension of both refraction and reflection principles.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb10c217e-0837-4d3f-89c5-6d9b36b54f81%2F09c3db71-e38b-4b82-a164-d95bafa26944%2Ff5gkjqg_processed.png&w=3840&q=75)
