I disagree. Something can be highly translucent or slightly translucent - I imagine there are even ways of measuring the degree of translucency, i.e., the amount of light it lets through. And tranparent means light can go through something without diffusion so you can see the image on the other side clearly. That doesn't mean it doesn't interrupt any of the light, or it would be invisible. Colored glass, for instance, can be transparent - light is absorbed, reflected and transmitted, but not diffused. Frost it, and it turns translucent rather than transparent.
