Final answer:
The cessation of buzzing noise from a TV after being hit is an example of resonance being disrupted. This concept, along with the Doppler effect and sound wave interference, are demonstrations of physics principles related to sound and waves.
Step-by-step explanation:
When you smack the television and the buzzing noise stops, this is an example of resonance being interrupted. The TV was likely emitting a sound at a resonant frequency, which sometimes is due to loose components vibrating. By hitting the TV, you might have temporarily stopped these components from vibrating, thus stopping the noise. Another physics concept related to waves is the Doppler effect, demonstrated when you hear the pitch of a motorcycle change as it passes by. The Doppler effect is due to the change in frequency of the sound waves reaching the observer as the source moves relative to the observer.
Furthermore, in some rooms, the interference of sound waves can cause certain areas to have louder or quieter sounds because of the waves constructively or destructively interfering with each other. This can happen with stereo systems, where the layout of the room and the position of the speakers can significantly affect the sound quality and volume in different areas.
