A coin kept at the bottom of a vlass bowl foll of water appears to be higher than it actually is .with the help of labeled digrams , explain why this happened
Dear student
Let there be a coin at the bottom of a beaker filled with water. Now, rays of light from point A on the coin will bend away from the normal as they emerge from a denser medium to a lighter medium i.e. from water to air. These rays will then appear to have came from the point A' that is exactly above A. Thus, A' is the virtual image of A. In the same way, each point on the dipped coin will have a corresponding virtual image above it. Due to this phenomenon, the coin appears at a point higher than where it actually is placed.
