Consider the following statements:
1. I. If a person looks at a coin which is in a bucket of water, the coin will appear to be closer than it really is.
2. II. If a person under water looks at a coin above the water surface, the coin will appear to be at a higher level than it really it.
Which of the above statements is/are correct?
Correct Answer: Option A
Explanation
1. Statement I: Describes observing a coin in a bucket of water. Due to the refraction of light as it travels from the denser medium (water) to the rarer medium (air) before reaching the observer's eye, the light rays appear to diverge from a point shallower than the actual depth of the coin. This makes the coin appear closer (at a shallower depth) than it really is. Statement I is correct.
2. Statement II: Describes an observer under water looking at a coin above the water surface. Light travels from the rarer medium (air, where the coin is) to the denser medium (water, where the observer is). When light enters a denser medium from a rarer medium, it bends towards the normal. To the observer under water, the rays appear to come from a point higher than the actual position of the coin. Statement II is correct.
3. Since both statements I and II are correct descriptions of phenomena related to the refraction of light at the air-water interface, option (A) is the correct choice.
