But waves are not objects, and there are some surprises in store.įirst, only part of the wave is usually reflected. After all, a material object such as a rubber ball would bounce back in the same way. In this chapter, we will concentrate mainly on reflection of waves that move in one dimension, as in figure c/1.ī / Circular water waves are reflected from a boundary on the left. Figure (a) shows a circular water wave being reflected from a straight wall. We use the word reflection, normally applied only to light waves in ordinary speech, to describe any such case of a wave rebounding from a barrier. Sound waves can echo back from a cliff, and light waves are reflected from the surface of a pond. No other species can master syntax, and even though chimpanzees can learn a vocabulary of hand signs, there is an unmistakable difference between a human infant and a baby chimp: starting from birth, the human experiments with the production of complex speech sounds. Speech is what separates humans most decisively from animals.
