Investigate whether light rays can travel around corners. Rotate circular walls, each of which has a single opening. Position the walls so that light from a central bulb can be seen by a person outside the walls. Notice whether light always travels in a straight line. This learning object is one in a series of six objects. Some of the objects are also packaged as two combined learning objects.
