UV waves can be polarized, while sound waves cannot. Polarization refers to the orientation of oscillations in a wave, specifically the direction of the electric field in electromagnetic waves like UV light. When discussing linear polarization, it indicates that the wave oscillates in a specific direction, such as along the y-axis. Sound waves, being mechanical waves that propagate through a medium, do not have a polarization state as they oscillate in the direction of propagation. Understanding these distinctions clarifies the nature of wave polarization.
