Detailed Solution

When a coin is placed in a bowl of water, when seen from above, it appears raised from its actual position.
Reflection:
When light rays fall on an object, there is a change in direction, and they turn back. This is 'reflection of light'.
Refraction:
When a ray of light passes from one medium to another, it deviates from its original path. This is the 'refraction of light'.
When a coin is placed in a bowl of water, when seen from above, it appears raised from its actual position. This is because of the 'Refraction of Light'. The light from the bottom of the bowl travels from water (a denser medium) to air (a rarer medium) before reaching the viewer.
