* Transparent: A transparent object allows light to pass through it completely, with no scattering or absorption. You can see clearly through a transparent object. Examples include clear glass and air.
* Translucent: A translucent object allows some light to pass through, but it's scattered, so you can't see clearly through it. You can see a blurry image or a distorted view. Examples include frosted glass, tissue paper, and the water with red food coloring.
Why the water with food coloring is translucent:
The red food coloring particles in the water scatter the light that passes through it. Some light gets through, but it's not a clean, clear view. This scattering is why the water appears red, but you can't see objects clearly through it.
