Question

We can partially see through the fog but cannot see through the door because:

• A. door is transparent and fog is opaque
• B. door is brown in colour
• C. door is opaque and fog is translucent
• D. door is translucent and fog is transparent

Answer 1

The correct option is C door is opaque and fog is translucent

Those objects that completely block the light are known as opaque objects. Since they do not allow light to transmit, we cannot see through them. The door is an example of an opaque object that is why we cannot see through it.

Those objects that partially transmit the light are known as translucent objects. Fog is translucent because we cannot see through it clearly, or in other words, it partially blocks the light.
