The horizontal floor of a water reservoir appears to be 1.0m deep when viewed vertically from above. If the refractive index of water is 1.35, calculate the real depth of the reservoir
A
2.35m
B
1.35m
C
1.00m
D
0.35m
Verified Correct Answer: B.
Physical Principles & Numerical Solution
n = \(\frac{R.d}{A.d}\)
1.35 = \(\frac{R.d}{1}\)
R.d = 1.35m
