A ray of light travelling in air enters obliquely into water. Does
the light ray bend towards the normal or away from the normal?
Why?
Answers
Answer:
The ray will bend away from the normal
Explanation:
The ray of light bends away from the normal because it enters a new medium which has different refraction index as compared to air.
Answer 1 : When a ray of light travels from air into water obliquely, it bends towards the normal. This is because water is optically denser than air. On entering water, speed of light decreases and the light bends towards normal.
Answer 2 : The ray of light bends towards the normal.When a ray of light enters from an optically rarer medium (having low refractive index) to an optically denser medium (having high refractive index), its speed slows down and it bends towards the normal.Since water is optically denser than air, a ray of light entering from air into water will bend towards the normal.
