Find Period Of A Wave Math

The amplitude can be read straight from the equation and is equal to a.

Find period of a wave math. This is known as the period of trigonometric function. I only have the time and height arrays. Find period of trigonometric functions. The amplitude can be read straight from the equation and is equal to a.

What i would like is to calculate its period but i don t know how. The usual period is 2 π but in our case that is sped up made shorter by the 4 in 4x so period π 2 and the 0 5 means it will be shifted to the right by 0 5 lastly the 3 tells us the center line is y 3 so vertical shift 3. Y x t a sin k x ω t φ. Therefore the wave period is 0 0005 seconds.

To find the amplitude wavelength period and frequency of a sinusoidal wave write down the wave function in the form y x t asin kx ωt φ. The period of the wave can be derived from the angular frequency left t frac 2 pi omega right. Bullet the wave height does not depend on the period or the length there are some exceptions in which the influence of the period and the length are minute. Formula to calculate wave period from wave length λ and speed.

A wave has a frequency of 2000 hz determine its period. For this reason in mathematics you have to measure a function s period in angle units. As previously we have calculated frequency so for 0 3 hertz frequency the time period is 1 divided by 0 3 which is equal to 3 3 seconds. In the problems below we will use the formula for the period p of trigonometric functions of the form y a sin bx c d or y a cos bx c d and which is given by.

I was thinking of finding all the values of time x axis when the height of the wave y axis goes to 0 and then work from there. I have this wave plotted in matlab for 10 periods. To find the amplitude wavelength period and frequency of a sinusoidal wave write down the wave function in the form y x t a sin k x omega t phi. Grade 12 trigonometry problems and questions on how to find the period of trigonometric functions given its graph or formula are presented along with detailed solutions.

To measure the period of a wave take the inverse of frequency.
