उत्तर
Amplitude is the size of the vibration, and this determines how loud the sound is. A larger amplitude means a louder sound, and a smaller amplitude means a softer sound. Below is the diagram, which represents the soft and loud waves, respectively. The first one is a softer wave and the second one is a louder wave.
