29. Answer:
synthesis
P.4.f
4.1.1
As the train approaches, you hear a sound with a frequency slightly
higher than the actual pitch of the train’s horn. The waves emitted by
the train’s horn travel at a fixed speed through the air. The motion of the
train squeezes the waves closer together in the forward direction,
shortening their wavelengths. The waves strike your ear with a
frequency greater than that emitted by the horn. As the train moves past
you, the wavelength of the waves increases, and as it moves away, the
waves are stretched farther apart and strike your ear at a lower
frequency. This is called the Doppler effect.
30. Answer:
synthesis
P.4.f
4.1.1
Wave interference is the result of two or more waves combining. When
they combine in phase—that is, with crests overlapping crests and
troughs overlapping troughs—the resulting wave has greater amplitude.
This is constructive interference. When overlapping is of crest on trough,
cancellation or diminishing of the wave results. This is destructive
interference.
