2024年3月7日 · If both amplitude and frequency are important for calculating the power of a sound wave, why is it that when it comes to calculating decibels, frequency does not matter? …

2007年5月19日 · The frequency of the sound depends on how fast the diaphragm moves back and forth (frequency of its oscillation). The amplitude of the sound wave (loudness of the …

2016年11月11日 · It was arrived at without reference to the amplitude or frequency and is true so long as the interaction between elements is harmonic (linearly proportional to displacement). …

2017年4月22日 · I think a frequency spectrum is a plot of frequency versus power (usually in decibels, in engineering). The power will be measured in a narrow passband which is swept …

2011年8月11日 · The Amplitude is now the density of particles, each particle having the minimum measurable amplitude and only differing in frequency. It is just a point of view. Aug 11, 2011

2008年12月9日 · [SOLVED] Finding the Amplitude of a spring (Simple Harmonic Motion) First post here at PF, so forgive me if I make a faux pas. I'm trying to study for an upcoming …

2006年6月15日 · You will notice that the frequency is inversely proportional to the mass: if the mass doubles, then the frequency is divided by [itex]\sqrt{m}[/itex], the object moves more …

2012年1月30日 · (c) Amplitude will decrease but frequency stays the same (d) Only the frequency changes since the mass is now different (e) Both the amplitude and the frequency will …

2007年2月9日 · However, the frequency of a sound wave also plays a role in the energy required. Higher frequency waves have more cycles per second, which means they also require more …

2020年8月31日 · When the object is in an evacuated container, the motion is simple harmonic motion, with an amplitude of 0.10 m. When air is allowed into the container, the amplitude …
