Study Notes

Light Reflection

Light reflects off surfaces with low absorption rates, making them appear brighter.
Surfaces with high absorption rates, like wood, absorb light instead of reflecting it, making them less reflective.

Mirrors and Reflection

A mirror's smooth surface allows it to reflect light well, helping the shop manager watch customers and the dentist examine patients' teeth.
When light reflects off a surface, it bounces back into our eyes, allowing us to see an image.

Surface Texture and Light Reflection

Surface texture affects how well a material reflects light; smooth surfaces reflect better than rough ones.
A mirror's smooth surface makes it a good reflector of light, enabling it to show clear images.

Characteristics of Reflective Materials

Materials with low absorption rates and smooth surfaces are better at reflecting light.
A mirror's reflective property makes it suitable for showing clear images.

How Mirrors Work

When light reflects off an object into our eyes, we can see its image.
A mirror's ability to reflect light so well makes it an effective tool for seeing our own image.
