Are windows transparent translucent opaque or luminous?

Answer 1

Windows are typically transparent, allowing light to pass through while enabling a clear view of the outside. However, some windows may have translucent properties if they are frosted or treated, diffusing light but not providing a clear view. Opaque materials, on the other hand, do not allow light to pass through at all. Luminous refers to objects that emit their own light, which does not apply to standard windows.
