Both waves can have interference, reflection, and diffraction.
Wave interference is a phenomenon that occurs when two waves meet while traveling along the same medium. The interference of waves causes the medium to take on a shape that results from the net effect of the two individual waves upon the particles of the medium.
Wave reflection happens when a wave reaches the boundary between one medium and another medium, a portion of the wave undergoes reflection and a portion of the wave undergoes transmission across the boundary.
Wave diffraction<span> involves a change in direction of waves as they pass through an opening or around a barrier in their path.<span> </span></span>
