What is the difference between opaque, translucent, and transparent materials?

Back

Opaque materials do not allow light to pass through, translucent materials allow some light but not clear images, and transparent materials allow light to pass through clearly.

Front

What is the role of light in determining the properties of materials?

Back

Light interacts with materials to determine whether they are opaque, translucent, or transparent based on how much light is transmitted.

Front

How does the thickness of a material affect its transparency?

Back

Generally, thicker materials are more likely to be opaque, while thinner materials may be transparent or translucent.

Front

What happens to light when it hits an opaque object?

Back

When light hits an opaque object, it is either absorbed or reflected, preventing it from passing through.
