So this function has a period equal to 8 and an amplitude equal to positive 1/2.
How do you find amplitude?
Amplitude Formulay = A s i n ( ω t + ϕ ) where, y is the displacement of the wave in meters. A is the amplitude of the wave in meters. ... y = 5 sin where x and y are in meters. Find the value of Amplitude. Given:y = 5 sin The equation is in the form of.y = A sin Henceforth, the amplitude is A = 5.

What is period and amplitude?
Amplitude: The distance from the center of motion to either extreme. Period: The amount of time it takes for one complete cycle of motion.
What is the period of a wave?
Wave Period: The time it takes for two successive crests (one wavelength) to pass a specified point. The wave period is often referenced in seconds, e.g. one wave every 6 seconds.
What is the amplitude of a graph?
The Amplitude is the height from the center line to the peak (or to the trough). Or we can measure the height from highest to lowest points and divide that by 2. The Phase Shift is how far the function is shifted horizontally from the usual position.
What is the amplitude of a sine function?
The amplitude of the sine and cosine functions is the vertical distance between the sinusoidal axis and the maximum or minimum value of the function. In relation to sound waves, amplitude is a measure of how loud something is.
What is amplitude math?
The amplitude of a function is the amount by which the graph of the function travels above and below its midline. When graphing a sine function, the value of the amplitude is equivalent to the value of the coefficient of the sine.
How do you find the period of a function from a graph?

As x increases our slope is positive here our slope is negative here.MoreWell here our Y is decreasing. As x increases our slope is positive here our slope is negative here. So this isn't the same point on the cycle. We need to get to the point where Y.
How do you find the period of a wave on a graph?
The period of a wave can be measured by choosing any time on the graph to be the initial time, and the time it takes to return to that position while heading in the same direction as the final time. Therefore, the period can be measured as the time between crests (maximum amplitude), troughs (minimum amplitude), etc.
What is the period of a graph?
Any one full pattern in the graph is called a cycle, and the length of an interval over which a cycle occurs is called the period.
How do you find the amplitude of a sound wave?
Intensity(I) of a wave at a point of the medium is measured as the amount of sound energy passing per second normally through unit area at that point. Its unit is Wm−2. Minimum intensity of sound wave audible to human ears is 10−12 Wm−2. Also, I∝A2 where, A is the amplitude.
How do you find amplitude on a graph?
The Amplitude is the height from the center line to the peak (or to the trough). Or we can measure the height from highest to lowest points and divide that by 2.
What is an amplitude in physics?
amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path.
How do you find the amplitude of a sine wave?
The amplitude of the sine function is the distance from the middle value or line running through the graph up to the highest point. In other words, the amplitude is half the distance from the lowest value to the highest value.
