When a ray of light travels from a denser medium to a rarer medium, it bends:
Snell's Law:
A
Towards the normal
B
Away from the normal
C
Along the normal
D
No bending occurs
Answer and explanation
Correct Answer: B — Away from the normal
When light travels from denser to rarer medium, the refracted ray bends away from the normal because speed increases. This follows Snell's law: .
