### Understanding Refraction of Light

When a laser beam passes from air (a less dense medium) into water (a denser medium), it experiences refraction, which is the bending of light as it changes speed entering a different medium.

1. **Index of Refraction**: The index of refraction for air is approximately 1.0, while for water, it is about 1.33. Since light travels faster in air than in water, this difference in density causes the light to refract.

2. **Behavior of Light**: According to Snell's Law, when light enters a denser medium, it bends towards the normal line (an imaginary line perpendicular to the surface at the point of incidence).

3. **Conclusion**: Since the laser beam moves from a less dense medium (air) into a denser medium (water), it will bend towards the normal.

### Final Answer
The laser beam is bent **towards the normal** when it passes from air into water.
