-
2.When the tuning fork in the figure below is made to vibrate, how does the pattern of the coils of the spring change?
- A.The coils remain evenly spaced with no visible change.
- B.The coils exhibit a wave pattern with compressions and rarefactions.
- C.The coils stretch uniformly along the entire length of the spring.
- D.The coils twist into a spiral pattern due to rotational motion.
-
3.What phenomenon occurs when a body vibrates with increased amplitude due to a periodic force matching its natural frequency?
- A.Refraction
- B.Resonance
- C.Diffraction
- D.Interference
-
4.Which property of waves is essential for their use in echo depth sounding?
- A.Waves must be visible to the human eye.
- B.Waves must travel undeviated over long distances and form a narrow beam.
- C.Waves must have a frequency below 20 Hz.
- D.Waves must be absorbed quickly by the medium.
-
5.Why does a tuning fork have two prongs?
- A.To produce a louder sound by mutual reinforcement of vibrations.
- B.To balance the fork and prevent it from toppling.
- C.To increase the frequency of the sound produced.
- D.To allow the fork to vibrate at multiple frequencies.
