Assertion: a coin, not visible before, becomes visible after some water is poured into the cup. Reason: light rays bendaway from the normal as they move from water to air select the correct answer (a) Both A and R are true and R is the correct explanation of the Assertion. (b) Both A and R are true and R is the correct explanation of the assertion
. (c) A is true but R is false. (d) A is false but R is true. ​

Answer 1

When the rays of light from the coin travel from denser medium to rarer medium, the refracted rays bend away from the normal. The point from which the refracted rays appear to come gives the apparent position of the coin. Since the rays appear to come from a point above the coin , it appears to be raised .

Hence , when a coin placed in a bowl of water and seen from above, it appears raised from its position !
