A fish inside a pond appears to be at a depth of 1.5m when viewed vertically from above. The refractive index of the water in the pound is 1.3. Calculate the apparent displacement of the fish
- A. 2.50m
- B. 1.95m
- C. 1.50m
- D. 0.45m
Correct Answer: D. 0.45m
Explanation
Real depth = n x apparent depth = 1.3 x 1.5 = 1.95m
Apparent displacement = 1.95 - 1.5 = 0.45m
