Materials can be classified by their appearance into categories such as lustrous and non-lustrous. Lustrous materials are shiny and reflect light, like metals such as gold, silver, and aluminum. On the other hand, non-lustrous materials do not shine and have a dull appearance, like wood, rubber, and chalk. Additionally, materials can be classified as transparent, translucent, or opaque based on how they allow light to pass through. These classifications help in understanding the material’s properties and choosing them for specific uses.
