Opaque materiels

What happens to light when it strikes an opaque material?

Light is either absorbed by the material's electrons or reflected off the surface. It is not transmitted through the material.

Why are metals opaque and shiny?

Metals are opaque because their free electrons reflect light, preventing it from passing through. This reflection also gives metals their shiny appearance.

How do non-metallic opaque materials like wood or stone interact with light?

Non-metallic opaque materials absorb the light energy, exciting their electrons. The energy is then converted into heat, preventing the light from passing through.

Why do metals reflect light so well?

Metals reflect light because they have free electrons that move in response to the electromagnetic wave of the light, reflecting it back and giving metals their shiny appearance.

What is the difference between opaque and transparent materials?

Opaque materials block light by absorbing or reflecting it, while transparent materials allow light to pass through without significant absorption.
