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