Translucent means light passes through the medium, but the light is diffused so that object beyond cannot be seen clearly.
Transparent means that light passes through the medium and is not diffused and objects beyound can be seen clearly.
Not exactly. A solid can be transparent and translucent also. What opaque means is no quanta can pass through it. So yes.
