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. Do you know of any other transparent materials? The most common one, with which we are familiar, is air. Another is clear water.
On the other hand, some materials do not let light pass through them at all. They stop the light waves just as you would-catch a ball that was being thrown to someone standing between you. Such materials are called opaque. Men' s bodies, like steel, rock, concrete or even cardboard, are opaque and do not permit the light to pass through. An opaque body casts a shadow.
The title that best expresses the ideas of the passage is ______.
A.Why are there shadows
B.The transparent materials
C.How to cast a shadow
D.Shadows and light waves
It's similar to an ordinary record,except that it's read by a laser beam,and the information recorded on the aluminium is digital.
The makers claim that a CD can reproduce the original sound perfectly,without any distortion or background hiss. As the system is computerized,there's no loss of quality between the studio master and the record you buy.
Also,a CD is much tougher-than a vinyl(乙烯基)record,so it doesn't need such careful handling. Dust and dirt won't damage it,and as there's no contact between the laser and the disc, it will never wear out.
