A swimming pool is 2.1m deep. If it contains water of refractive index 1.3, calculate the apparent depth of pool
- A. 3.4m
- B. 2.7m
- C. 1.6m
- D. 0.8m
Correct Answer: C. 1.6m
Explanation
n = \(\frac{\text{real depth}}{\text{apparent depth}}\)
1.3 = \(\frac{2.1}{\text{apparent}}\)
A.D = \(\frac{2.1}{1.3} = 1.6\)
