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
Verified Correct Answer: D.
Physical Principles & Numerical Solution
Real depth = n x apparent depth
= 1.3 x 1.5 = 1.95m
Apparent displacement = 1.95 - 1.5 = 0.45m
