No, dense fog is not opaque; it is translucent.
While dense fog significantly reduces visibility, it doesn't completely block light like an opaque object would. Objects behind the fog can still be seen, although they appear blurred and indistinct.
Here's a breakdown:
- Opaque: An opaque object blocks all light from passing through it. You cannot see anything behind an opaque object. Examples include a brick wall or a solid metal sheet.
- Translucent: A translucent object allows some light to pass through, but the light is scattered, so objects behind it are not clearly visible. Fog, frosted glass, and some fabrics are examples of translucent materials.
- Transparent: A transparent object allows light to pass through without significant scattering, allowing you to see objects behind it clearly. Examples include clear glass and clean water.
Because you can still perceive light and shapes through dense fog, even if they are blurred, it is classified as translucent, not opaque.
