What are the characteristic of compressional waves? 1 Acoustic propagation wave theory. Longitudinal or compression waves are defined as waves where the particle motion is in the same direction in which the wave is propagating. The oscillations in pressure are sinusoidal in nature and are characterised by their frequency, amplitude and wavelength (Figure 9.1). What […]
What is vacuum pressure example?
What is vacuum pressure example? Vacuum Examples A vacuum cleaner sucks up debris because it creates a pressure difference between the area to be cleaned and the suction tube. Your lungs intake air when your diaphragm drops, creating a partial vacuum in the alveoli of the lungs, causing air to rush in. Is vacuum measured […]
