The amplitude of a wave refers to the maximum amount of displacement of a particle on the medium from its rest position. A periodic function is a function whose graph repeats itself identically from left to right. This function has an amplitude of 1 because the graph goes one unit up and one unit down from the midline of the graph. a = 1 a = 1. b = 1 b = 1. c = 0 c = 0. d = 0 d = 0. The Period goes from one peak to the next (or from any point to the next matching point):. For example, if your function's range (y values) is between -2 and +2, then the amplitude is 2. Some functions (like Sine and Cosine) repeat forever and are called Periodic Functions.. Displacement-time A displacement-time graph shows how the displacement of one point on the wave varies over time. Let b be a real number. Amplitudes are always positive numbers (for example: 3.5, 1, 120) and are never negative (for example: -3.5, -1, -120). The amplitude of the sine function is the distance from the middle value or line running through the graph up to the highest point.
