Amplitude and wavelength are not directly proportional, as amplitude is a part of wavelength. A sensor detects the time it takes for the waves to return and then determines the distance an object is from the camera. A higher amplitude of a sound wave means its loudness is higher, and a lower amplitude means lower loudness. When the amplitude is this small, it does not affect the period of the pendulum. The average amount of energy passing through a unit area per unit of time in a specified direction is called the intensity of the wave. The amplitude carries energy in a wave between specific points, and the frequency is related to the period. 1 Why does amplitude not affect wave speed? Wave speed = frequency x wavelength. The factors which change the nature of amplitude of a wave are. A change in energy is the most likely cause of the amplitude variation, but it might also be a change in wave speed. Why is energy proportional to amplitude squared? When the amplitude increases in a wave, it carries more energy and gains higher intensity; in terms of sound waves, if the intensity is high, then the quality of sound will be loud.
