When a light ray travels from an optically rarer medium (air) to an optically denser medium (water), its speed decreases.

According to Snell's law, $\mu_1 \sin i = \mu_2 \sin r$.

Since the refractive index of water is greater than that of air (\mu_2 > \mu_1$), we have \sin r < \sin i$, which implies $r < i$.

Thus, the refracted ray bends towards the normal.

Answer: bending towards the normal
