One hertz (Hz)
The number of times an objct vibrates in one second is called frequency
The period of vibration is the time it takes to complete one full cycle of vibration. In this case, since the wave vibrates 3 times each second, the period of vibration would be 1/3 seconds per cycle.
The word for "number of vibrations per second" or "cycles per second" is frequency. Otherwise, you might be looking for the density and bulk modulus of the medium, and the intensity of the energy... which will establish the natural frequency of a system.
Hertz, abbreviated "Hz". The unit of Hz is "per second".
The period is the reciprocal of the frequencey. Just divide 1 / (frequency).
The frequency of something vibrating one million times per second is 1 MHz (megahertz).
Lower frequency equates to a longer wavelength, so the 340 Hz tuning fork would emit a longer wavelength sound.
Yes. Specifically, the number that pass a point in one second.
The frequency would be 1 million Hertz.
pujols because a-rod has reassumed this position as the number one player and number one of all time
There is no such thing as vibrates or non-vibrates. Vibration is a concept when dealing with sound waves. However, one may mean vertibrates and invertibrates. Vertibrates are those that have backbones and invertibrates do not.
Feet refers to a distance while seconds is time, so you can't say that there are a certain number of feet in one second. You can however say that you travel a certain number of feet in one second, but that number depends on the velocity that you are traveling at.
