When water is very still, its surface is smooth and flat, which means it can act like a mirror and show a clear reflection.

How to see it:

Look into a river or a puddle on a day when there is no wind. You can see a reflection of the sky, clouds, and buildings around it.

💡 Fun Facts

  • The smoother the surface of the water, the clearer and sharper the reflection will be.
  • If the wind blows and makes ripples, the reflection gets wobbly and distorted because the light is bouncing off in lots of different directions.
  • The famous landmark Stonehenge was built near the River Avon, and some people think it was positioned to create beautiful reflections in the water.
