प्रश्न
A ray of light travelling in glass emerges into air. State whether it will bend towards the normal or away from the normal.

उत्तर
We know that glass is a denser medium and air is a rarer medium. When a ray of light travels from a denser medium to a rarer medium, it bends away from the normal. So, the ray will bend away from the normal in the given case.
