Sound Waves Push Particles

The lower the pitch the less movement of particles. the higher the pitch the more movement in particles. particles move by vibration

of sound. sound waves manipulate particles into desired patterns on a microchip. Doesn't sound waves carry energy. It has very tiny

amount of mass. sound waves are vibrating molecules and they must have momentum.acoustic waves can also push an object.Sound waves

have momentum and dispersion a phase and a group velocity. Phonons carry pseudomomentum. Summed up the momentum of all phonons

usually cancels to 0.Otherwise the center of mass of the crystal would have to move .Sound is a mechanical wave which results from

back and forth vibration of the particles.The particles are parallel to the direction of the energy transport.
