    Answer

    The table tennis ball represents a particle in the air. when it touches the vibrating tuning fork it’s pushed away like an air particle. as the particle and the tuning fork separate the region between it represents a area of low pressure. when the table table tennis ball moves closer to the tuning fork it represent an area of higher pressures. if the areas high pressure and low pressure is plotted on a graph it would form a wave.
