In general, when the amplitude of a wave increases, the frequency of the wave remains unchanged. The amplitude of a wave refers to the maximum displacement or height of the wave from its equilibrium position, while the frequency represents the number of complete cycles or oscillations of the wave that occur in a given time.
In simple terms, think of a wave as a wiggling or vibrating motion. The amplitude determines how high or low the wave reaches, while the frequency determines how quickly the wave wiggles or vibrates.
When you increase the amplitude of a wave, you are essentially making the wiggles or vibrations more pronounced. However, the rate at which the wave wiggles, or the number of complete cycles it completes per unit of time (frequency), does not change. So, increasing the amplitude does not affect the frequency.
It's important to note that there can be cases where changing the amplitude might indirectly affect the frequency in certain systems or phenomena, but this is not a general rule. In most cases, amplitude and frequency are independent properties of a wave.
