- 1 The period is the time it takes to go through one complete cycle.  In the interactive, when the radius of the circle was `50` units then the curve went up to `50` units and down to `-50` units on the y-axis. This quantity of a sine curve is called the amplitude of the graph.

Amplitude, Period, Phase Shift   and Frequency In words: 1  the 2 tells us it will be 2 times taller than usual, so Amplitude = 2. 2  the usual period is 2π, but in our case that is sped up (made shorter) by the 4 in 4x, so Period = π/2.

Amplitude And Period Amplitude and period are important in the study of music and acoustics; amplitude indicates the energy, or loudness, of a sound and the period determines its pitch (pitch, or frequency, is the inverse of the period). Amplitude is the height from the mean, or rest, value of the function to its maximum or minimum.The period is the distance required for the function to complete one full cycle. For the sine function, the amplitude is given by and the period is defined as. The same is true for a cosine function.mplitude is the height from the mean, or rest, value of the function to its maximum or minimum.

Waves and Sound The period of a wave or a vibration is the time it takes for one complete back and forth vibration. The frequency of a wave or a vibration specifies the number of back-and-forth vibrations it makes in a given time. If the frequency of a vibrating object is known, its period can be calculates, and vice versa.uppose that a pendulum has a period of 1.5 seconds. It takes 1.5 seconds to make a complete back-and-forth vibration. This 1.5-second pendulum is longer in length than a 1-second pendulum.

Period of a Wave The length that a particle has traveled in one period of a wave is called wave length of the wave motion and denoted by the Greek letter $\lambda$ (pronounced as lambda). Now let us say that the particle completes 'f' cycles in a second. Therefore, we can write an equation as, f $\times$ T = 1.eriod of a Sine Wave. The wave motions of several phenomenons are sine waves or sinusoidal waves. That is when an object is rotating around a point, the height of the object at any time is the sine function of the angle made by the object with positive x-axis.

Sine wave A sine wave is a curve with this shape: This is a picture of a sine wave. All waves can be made by adding up sine waves. The sine wave has a pattern that repeats. The length of this repeating piece of the sine wave is called the wavelength. The wavelength can be found by measuring the length or distance between one peak of a sine wave and the next peak.

ANSWER KEY A period T is the time needed for one complete cycle of vibration to pass a given point. As the frequency of a wave increases, the period of the wave decreases.Frequency and Period are in a reciprocal relationship that can be expressed mathematically as: Period equals the Total time divided by the Number of cycles.1  Orbital period is the time for something to go round (orbit) something else.requency and Period are in a reciprocal relationship that can be expressed mathematically as: Period equals the Total time divided by the Number of cycles.

Period of a Wave It is generally represented by the letter T. Thus we can define time period as: The length that a particle has traveled in one period of a wave is called wave length of the wave motion and denoted by the Greek letter $\lambda$ (pronounced as lambda).Now let us say that the particle completes 'f' cycles in a second. Therefore, we can write an equation as, f $\times$ T = 1.t is generally represented by the letter T.

Wave Period: Definition & Formula The wave period is the measure of time it takes for the weave cycle to complete. We usually measure the wave period in seconds and represent it with the letter T. Before we find the period of a wave, it helps to know frequency of the wave, that is the number of times the wave cycle repeats in a given time period.

Wave Parameters: Wavelength, Amplitude, Period, Frequency & Speed While period is measured in seconds per cycle, frequency is measured in cycles per second. Consider our wave with a period of 2 seconds. Since the wave completes one cycle every two seconds, then its frequency is one half or 0.5 Hz.

- Amplitude. Amplitude is a measurement of the vertical distance of the wave from the average. The wave axis is the average height of the wave over one cycle, and is usually considered to be zero. Heights above and below the average are given positive and negative values, respectively. The wave shape shown below is called a sine wave. The maximum and minimum amplitudes of this sine wave are the heights measured from the wave axis (white line) to the top of the wave peak and bottom of the wave trough.

Frequency and Period of a Wave The period of a wave is the time for a particle on a medium to make one complete vibrational cycle. Period, being a time, is measured in units of time such as seconds, hours, days or years. The period of orbit for the Earth around the Sun is approximately 365 days; it takes 365 days for the Earth to complete a cycle.nswer: 0.0195 sec. Here is an example of a problem with a lot of extraneous information. The period is simply the reciprocal of the frequency. In this case, the period is 1/(51.2 Hz) which is 0.0195 seconds.

- What is the period of a sine cosine curve? Answer. The Period is how long it takes for the curve to repeat. As the picture below shows, you can 'start' the period anywhere, you just have to start somewhere on the curve and 'end' the next time that you see the curve at that height.

Define period, amplitude and phase shift, Mathematics Q. Define Period, Amplitude and Phase Shift? Ans. Period, amplitude and phase shift are used when describing a sinusoidal curve The period of a function is the smallest number p for which f(x + p) = f(x) for each x for which is defined. The function sin(x) repeats every degrees, sin (x +) = sin(x).t is also clear by the graph that 2p is the smallest number for which this is true. The period of sin(x) is 2π. The amplitude of a sinusoidal wave is the distance from the central axis (the x-axis in this case) and the maximum or minimum value of the wave.
