What is the period of a 100 Hz sine wave?

In the example above, f = 1/10 ms, or 100 Hz (100 cycles in one second).

How long is a 100 Hz wave?

4 meters
A 100-Hz sound wave has a wavelength of 4 meters.

How do you calculate the period of a wave?

The formula for period is T = 1 / f , where “T” is period – the time it takes for one cycle to complete, and “f” is frequency. To get period from frequency, first convert frequency from Hertz to 1/s. Now divide 1 by the frequency. The result will be time (period) expressed in seconds.

What is the periodic time of a sine wave?

For example, a sinusoidal waveform which takes one second to complete its cycle will have a periodic time of one second. Likewise a sine wave which takes five seconds to complete will have a periodic time of five seconds and so on.

What is the frequency of 100 hertz?

How many times does it vibrate in a minute? Therefore, the source of sound vibrates 100 times in one second.

What is the period of a 100 Hz wave?

The period is the reciprocal of the frequency. If the frequency is in Hz, the period is in seconds. What is the period of a wave with a frequency of 100 Hz and a wavelength of 2.0 m?

How is the period of a sine wave measured?

T = 0.625 seconds. A wave frequency is defined as ‘The total number of vibrations or oscillations made by the particles per unit time’ and is denoted by symbol ‘f’ and is measured by the unit Hertz or Hz. Thus the period of the sine curve is the length of one cycle of the curve.

How to calculate the period and frequency of a wave?

graph the wavelength may be determined. From the time graph, the period and frequency can be obtained. From both together, the wave speed can be determined. Source: y = A sin (2 π f T + φ ). Where ω = 2 π f and A is the amplitude and where f is the frequency of the wave measured in hertz. With this acoustical form we see that | B | = 2 π f.

What is the frequency of a 4 Hz wave?

A period can’t be 4 Hz; those are the wrong units. If the period is 1/(4Hz), then the frequency is 4Hz. If the period is 4 seconds, then the frequency is 0.25 Hz. They are inversely related. What is the wave frequency of a periodic wave of 40 nanoseconds?
