Here's a breakdown:

* Light travels in straight lines. When it encounters an object, it can be absorbed, transmitted, or reflected.

* Reflection is when light bounces off a surface. The angle at which the light hits the surface (the angle of incidence) is equal to the angle at which it bounces off (the angle of reflection).

* The type of reflection depends on the surface:

* Specular reflection occurs on smooth, polished surfaces like mirrors. The reflected light rays are all parallel, resulting in a clear image.

* Diffuse reflection occurs on rough surfaces. The reflected light rays scatter in all directions, making the surface appear dull.

Reflection is the reason we can see objects. Light from a source (like the sun or a lamp) bounces off the object and into our eyes, allowing us to perceive its shape and color.
