Reflection

Reflection and Refraction Of Light

Why Do We See Our Reflection In The Water?

Reflections are usually caused by shiny things, such as mirrors, that show a reversed image of whatever is placed in front of them. The image seems to be as far behind the mirror as the object is in front of it. Not only mirrors make reflections. Most objects reflect some of
the light that falls on them. In daytime we see familiar objects like grass, trees, and the sky only because they reflect light from the
Sun into our eyes.

When light rays bounce off a completely smooth surface, such as a still pool of water, a mirror, or even something like a shop window, we are able to see a very clear reflection on the surface. Every ray of light is reflected perfectly from the surface and bounces back in a regular way. The reflected image is very clear and sharp.
