To determine the amplitude using the period, time, and velocity, you would need to have additional information or measurements related to the specific wave. The period (T) represents the time it takes for one complete cycle of the wave, and the velocity (v) indicates the speed at which the wave propagates through the medium. However, without additional data or the specific equation of the wave, it is not possible to directly calculate the amplitude.
The amplitude (A) of a wave represents the maximum displacement of the wave from its equilibrium position. It is usually denoted as the distance from the equilibrium to the peak or trough of the wave. The specific amplitude value depends on the wave's properties and can vary.
If you have the equation of the wave, you can determine the amplitude from it. For example, in the case of a simple harmonic wave, the equation can be written as A*sin(2πt/T), where A is the amplitude, t is time, and T is the period. In this case, the amplitude A is directly given in the equation.
If you have measurements of the wave's displacement at specific points or the maximum displacement from the equilibrium position, you can use those measurements to determine the amplitude. However, simply having the period, time, and velocity is not sufficient to calculate the amplitude without further information or measurements.
