Changing the amplitude of a sine wave does not affect its period or frequency. The period of a sine wave refers to the time it takes for one complete cycle of the wave to occur. It is typically denoted by the symbol "T" and is measured in seconds. The frequency of a sine wave, denoted by the symbol "f," represents the number of complete cycles that occur in one second and is measured in hertz (Hz).
The relationship between period and frequency is given by the equation:
frequency = 1 / period
The amplitude of a sine wave, on the other hand, represents the maximum displacement or height of the wave from its equilibrium position. It determines the maximum value of the wave's oscillation. Changing the amplitude of a sine wave will alter its height but will not affect the time it takes for one complete cycle (period) or the number of cycles that occur per second (frequency).
