A student is observing a diagram showing the path of a ray of light passing through a glass prism. He would find that for all angles of incidence the ray of light bends:
पर्याय
towards the normal, while entering the prism and away from the normal while emerging from the prism
away from the normal while entering the prism and towards the normal while emerging from the prism
away from the normal while entering as well as while emerging from the prism
towards the normal while entering as well as while emerging from the prism

उत्तर
When a ray of light enters a glass prism, it travels from a rarer medium to a denser medium. So, the ray of light bends towards the normal.
When the ray of light emerges from the glass prism, it travels from a denser medium to a rarer medium. So, the ray of light bends away from the normal.
Hence, the correct option is A.
