Passage Two Look at a man walking down a street or road in’ the sunlight and you will see his shadow. If you watch two men walking in the sunlight and carrying a six-fool pane(窗玻璃片) of glass between them, you will see each man six feet apart, but there will be no shadow of the pane of glass. Shadows are easily explained since we know that light travels in a straight line. We also know that light waves pass through some bodies and not through others. When light strikes a body and passes through it unchanged, we call such a body or material transparent. Most glass is such a material, especially window glass, and it is for this reason that we do not see the shadow of the window pane which the men are carrying.

A. Light waves are beams of light.
