When the amplitude of a wave increases, the frequency of the wave remains unchanged. The frequency of a wave refers to the number of complete cycles (or oscillations) it completes in a given unit of time. It is typically measured in hertz (Hz), which represents the number of cycles per second.
On the other hand, the amplitude of a wave represents the maximum displacement or distance from the equilibrium position that the wave reaches during one cycle. In simpler terms, it measures the "height" or "intensity" of the wave.
So, when the amplitude of a wave increases, the wave's shape becomes taller or more intense, but it does not affect how many cycles the wave completes in a given time. The frequency remains constant, while the amplitude changes.
