Physics
A light ray suffers reflection and refraction at the boundary in passing from air to water. Draw a neat labelled diagram to show it.
Answer
Air is a rarer medium while water is denser medium than air. Therefore, when a ray of light travels from air to water (i.e rarer to denser) it bends towards the normal. Below diagram shows reflection and refraction suffered by a light ray at the boundary in passing from air to water:
