alleryWhen light passes from a rarer medium to a denser medium, it bends:
AAway from the normal
BTowards the normal
CParallel to the normal
DAlong the surface
Answer & Solution
Correct answer: B. Towards the normal
1. Light slows down in the denser medium.
2. By Snell's law, this means the refracted ray bends towards the normal.
3. Reverse direction (denser to rarer) would bend the ray away from the normal.
