Following our project Optical, now try to guess which objects of the class let in light and what not. We tried our hands, with a shoe, with a transparent glass and another orange, with a plastic bag with a chair and a table with a black cardboard with a white sheet, etc.
To remember best of all the objects that we verify, we made a list on the blackboard and the teacher told us that the objects that let light through are called transparent and not let it happen are called opaque.
the end, we conclude that things plastic, paper and glass tend to let the light, and the things of wood and concrete, no.
also discovered that the shadow of opaque objects is much stronger than that of the transparent, as even some of them nisiquera cast a shadow.
