A tank is filled with water to a height of 15 cm. If the refractive index of water is 1.33, the apparent depth of a needle lying at the bottom of the tank will be
- A 11.28 cm
- B 12.6 cm
- C 10.8 cm
- D 13.24 cm
Answer & Solution
Correct Answer
(A) 11.28 cm
Step-by-step Solution
Detailed explanation
\(d_{app} = \frac{d_{real}}{n}\) \(d_{app} = \frac{15 \text{ cm}}{1.33}\) \(d_{app} \approx 11.28 \text{ cm}\)
