When a ray of light travels from a denser medium to a rarer

SSC CGL2025Physics OpticsMedium

When a ray of light travels from a denser medium to a rarer medium, it bends:

Snell's Law:

$n_1 \sin\theta_1 = n_2 \sin\theta_2$

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: $n_1 \sin\theta_1 = n_2 \sin\theta_2$ .
