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: Option D
Explanation
Real depth = n x apparent depth
= 1.3 x 1.5 = 1.95m
Apparent displacement = 1.95 – 1.5 = 0.45m
