- 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. Know your physics concepts to weed through the extra information.

Frequency and Period Angular period, T, is defined as the time required to complete one revolution and is related to frequency by the equation: Since we know that the frequency of the second hand is 1 / 60 Hz, we can quickly see that the period of the second hand is 60 s. It takes 60 seconds for the second hand to complete a revolution, so the period of the second hand is 60 seconds. Period and angular velocity are related by the equation

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 ...

- Period refers to the time for something to happen and is measured in seconds/cycle. In this case, there are 11 seconds per 33 vibrational cycles. Thus the period is (11 s) / (33 cycles) = 0.33 seconds. 9.

Define period, amplitude and phase shift, Mathematics It 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.The phase shift of a curve is the shift, left or right, of the base curve.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.

Period of a Wave Period of a Wave. The wave travels through a medium that produce vibration in the medium. Thus, they travel through vibrations from one side to another side. The properties of wave are described by using some terms like wave frequency, wave number, wavelength, its time period, and velocity.t 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).

Period (physics) 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.

ANSWER KEY The period of a pendu-lum is defined as the time it takes to complete one full oscilla-tion. This relationship is given as follows [2]: T =2*π L / g In rotational motion, it is often questioned how the period of the pendulum differs when various factors concerning the pendulum are changed.

- Best Answer: to find the period you divide 2π by the multiplier of the x or θ. for example the period of cos(2θ) would be 2π/2 which would equal π. so in y=cost(θ/4) the period would be 2π/ 1/4 which, because your dividing by a fraction, becomes 2π x 4/1 or 8π. hope this helps!

Period of a Function If we extend the function h to all of R by the equation, ${h}(t+2)={h}(t)$. The graph of the function is shown below. The distance between the repetition of any function is called the period of function. For a trigonometric function, the length of one complete cycle is called period. For the graph of any trigonometric function, we can take x = 0 as the starting point. In general we have three basic trigonometric functions like sin, cos and tan function, having 2$\pi$, 2$\pi$ and $\pi$ period respectively.

What Is a Period in Math Terms? In math terms, the period of a function is the smallest interval over which the values of the function recur. For example, the sine function, sin(x), has a period of 2pi, as sin(x + 2pi) = sin(x) for all values of x. Continue Reading.

Planet The period of one revolution of a planet's orbit is known as its sidereal period or year. A planet's year depends on its distance from its star; the farther a planet is from its star, not only the longer the distance it must travel, but also the slower its speed, because it is less affected by its star's gravity.
