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
Correct Answer: Option B
Explanation
n = (frac{R.d}{A.d})
1.35 = (frac{R.d}{1})
R.d = 1.35m
