How light moves?
Light moves in a straight line, and its rays indicate the path traveled by it. The material through which light travels is called the medium.

Opaque objects are those through which we cannot see anything. Opaque media don’t allow light to pass through them.
Define transparent?
Transparent objects are those through which we can see clearly. Transparent media are those that permit all light to pass through them.

A translucent object is one that allows us to see some light through it, and cannot see the objects on the other side clearly. A translucent medium is one that only allows a portion of the light reaching it pass through.
