If wave completes 20 vibration in 2.5 seconds what is its frequency?
The frequency is the number of vibrations in 1 second, so just divide 20/2.5 = 8 vib/sec .
What is the number of vibrations that occur in a 1-second time interval.?
It is the frequency.
What unit measures vibration?
Vibration has amplitude and frequency, usually defined by acceleration and cycles per second (Hertz). It is measured with an accelerometer.
Why are the units of frequency expressed in reciprocal units?
Frequency is defined as the number of repetitions made in one second. In case of pendulum the repetition is called oscillation. In case of a tuning fork, the repetition is known to be vibration. In case of a wheel, the same repetition is said to be rotation. In case of planet going around the sun, that one is named as revolution. So, the number of oscillations, vibrations, rotations, revolutions per second in known as frequency. Thus, as the number has no unit and time has second as unit we get the unit for frequency as second -1
What is the number of vibrations that occur in a 1-second time interval is called?
It is called the frequency. The SI unit is the Hertz. One Hertz is one cycle per second.
What does the frequency of vibration mean?
the number of vibrations made by the vibrating body in one second is known as its frequency
What is it called when vibrations cause a second object to vibrate?
When vibrations from one object cause another object to vibrate, it is called resonance. Resonance occurs when the natural frequency of the second object matches the frequency of the vibrations of the first object, resulting in increased amplitude and sustained vibrations in the second object.
A wave travels an average distance of 1 meter in 1 second with a frequency of 1 hertz Its amplitude is?
A wave travels an average distance of 1 meter in 1 second with a frequency of 1 hertz Its amplitude is that there is not enough information to say. A 60 vibration per second wave travels 30 meters in 1 second, its frequency is 60 hertz and it travels 30 meters per second.
If wave completes 20 vibration in 2.5 seconds what is its frequency?
The frequency is the number of vibrations in 1 second, so just divide 20/2.5 = 8 vib/sec .
What do you call the number of vibrations per second?
Vibrations a second are measured in Hertz.
Measured in vibrations per second?
frequency
How fast does something have to vibrate to produce sound?
The human ear can sounds between about 20 and 20,000 vibrations per second. Anything that produces this kind of vibration will be heard. Note that this may include secondary vibrations; for example, if a string has its main vibration at 15 Hz (vibrations per second), then it will also have secondary vibrations at 30 Hz. 45 Hz., etc.The human ear can sounds between about 20 and 20,000 vibrations per second.

What is the measure of how many times an object vibrates per second?
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.
When you make the note lower what do you change?
The frequency - that is, the number of vibrations per second. Lower notes have less vibrations per second.
What is the number of vibration that occur in a second time interval?
frequency
What makes the diffrent sounding pitches on a stringed instrument?
Pitch is related to the frequency of the vibration. Frequency means the number of vibrations per second that a given string is tuned to produce. Today in most applications 'standard' pitch is centered around A=440, which means that a frequency of 440 cycles per second gives the musical pitch A.
What do you call the measure of nunber of vibrations per second?
That's their frequency .
