Here's why:
* Light is a wave: Light travels in the form of electromagnetic waves.
* Waves interact with matter: When light waves encounter the surface of an object, they interact with the atoms and molecules in that surface.
* Reflection: This interaction causes the light waves to change direction and bounce back, which we perceive as reflected light.
This is how we see most objects. The light from a source (like the sun or a lamp) bounces off the object and into our eyes, allowing us to perceive its shape, color, and texture.
