You need to know the mass of the earth and it's natural freqeuncy. The answer is usually about 10 Hz. It goes "dong" at about ten times per second, as opposed to the human ear, which can start to detect "dong"s at 2000 Hz.

The hertz (symbol: Hz) is the SI unit of frequency. In English, hertz is used as both singular and plural.

You might think 200 Hz at first since 900-700 = 200. But the question is how do you get the 700 resonance from a 200 Hz fundamental frequency?  A musical instrument wouldn't do this -if it had 200 Hz as a fundamental frequency, then it would have 400, 600, 800, 1000 ... as resonances, not 700 and 900. \n\nOne answer might be if the object is a closed cylinder. The sound propagates thought the air column and is reflected by the closed end. Thus only odd harmonics are generated (see the link for a drawing to help understand this). So if you have closed column with a fundamental frequency of 100 Hz, then you would see 100, 300, 500, 700, 900 ... Hz resonances - so you can get the 700 and 900 Hz resonances that you describe with nothing in between!!

Sound, as in sound waves?\n\nAmplitude, wavelength, pitch, frequency, longitudinal, vibration, echo, decibel, resonance.
387857
An electronic instrument that produces an instantaneous trace on the screen of a cathode-ray tube corresponding to oscillations of voltage and current.

Look for caliper (spelling counts).  Specifically, Vernier Caliper, and micrometer.  \n\nThose are the two major precision measuring tools.  Try the starrett.com web site.  They have a sterling reputation for quality.

The unit used to measure the loudness or intensity of sound is the deciBel dB, named after the inventor of the telephone Alexander Graham Bell

A laser Doppler Vibrometer is based on the principle of the detection of the Doppler shift of coherent laser light, that is scattered from a small area of the test object. The object scatters or reflects light from the laser beam and the Doppler frequency shift is used to measure the component of velocity which lies along the axis of the laser beam.

None, sound is a wave not a particle. Sound is just a wave of vibrations travelling through atoms.

Music is organized sound, so I think the answer would be "irregular vibration patterns".  These links should help.

human beings are able to perceive sounds between 20 and 20000 hertz.the sounds having frequencies above the 20 kilo hertz mark are termed as ultra sonic sounds. And for futher information the sounds having frequencies below 20 hertz are termed as infrasonics. though all this may vary from animals to humans and in humans too because of the different biological formations. BY THIS VARIATION I MEAN THE VALUE OF THE PERCEIVENCE OF SOUNDS FREQUENCY MAY VARY.

Actually Decibels is a logarithmic scale so not as simple as normal calcualtion... the actual answer is 100 times louder...\n\nthe scale which is frequently used by physicists to measure intensity is a scale based on multiples of 10. This type of scale is sometimes referred to as a logarithmic scale. The scale for measuring intensity is the decibel scale. The threshold of hearing is assigned a sound level of 0 decibels (abbreviated 0 dB); this sound corresponds to an intensity of 1*10-12 W/m2. A sound which is 10 times more intense ( 1*10-11 W/m2) is assigned a sound level of 10 dB. A sound which is 10*10 or 100 times more intense ( 1*10-10 W/m2) is assigned a sound level of 20 db. A sound which is 10*10*10 or 1000 times more intense ( 1*10-9 W/m2) is assigned a sound level of 30 db. A sound which is 10*10*10*10 or 10000 times more intense ( 1*10-8 W/m2) is assigned a sound level of 40 db. \n\nSo something 90db is 10*10*10*10*10*10*10*10*10 times more intense or  1,000,000,000 times more intense.\nSomething 100db would be  10,000,000,000 (10 times louder)\nSometing 110db is  100,000,000,000 (10x10 times louder)\n\n\n\n\nObserve that this scale is based on powers or multiples of 10. If one sound is 10x times more intense than another sound, then it has a sound level which is 10*x more decibels than the less intense sound. The table below lists some common sounds with an estimate of their intensity and decibel level.\n\nSource Intensity Intensity \nLevel\n # of Times \nGreater Than TOH\n \nThreshold of Hearing (TOH) 1*10-12 W/m2 0 dB 100 \nRustling Leaves 1*10-11 W/m2 10 dB 101 \nWhisper 1*10-10 W/m2 20 dB 102 \nNormal Conversation 1*10-6 W/m2 60 dB 106 \nBusy Street Traffic 1*10-5 W/m2 70 dB 107 \nVacuum Cleaner 1*10-4 W/m2 80 dB 108 \nLarge Orchestra 6.3*10-3 W/m2 98 dB 109.8 \nWalkman at Maximum Level 1*10-2 W/m2 100 dB 1010 \nFront Rows of Rock Concert 1*10-1 W/m2 110 dB 1011 \nThreshold of Pain 1*101 W/m2 130 dB 1013 \nMilitary Jet Takeoff 1*102 W/m2 140 dB 1014 \nInstant Perforation of Eardrum 1*104 W/m2 160 dB 1016

Sure.  An oscilloscope ought to do the trick.
