No, sound waves do not have mass. Sound waves are mechanical waves that propagate through a medium, such as air, water, or solids, by transferring energy from one particle to another. They consist of oscillations of particles in the medium, creating regions of compression and rarefaction as the wave travels.
Mass is a property of matter and refers to the amount of matter contained in an object. Sound waves, although they carry energy, do not have mass because they are the result of the collective motion of particles within the medium. The particles themselves oscillate back and forth but do not undergo a net displacement in the direction of wave propagation.
It's important to note that although sound waves do not possess mass, they can exert pressure and transfer energy to objects they encounter, which can have physical effects.
