A ray of light travelling in air enters obliquely into water. Does the light bend towards or away from the normal? Why? Draw a ray diagram to show the refraction of light in this situation.
The light ray will bend towards the normal because air is a rarer medium and water is a denser medium. Since light is travelling from rarer to a denser medium, So, it will bend towards the normal.
The ray diagram to show the refraction of light from air to water is as follows:
