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 involves a change in direction of waves as they pass through an opening or around a barrier in their path.
Which pair of properties apply to both sound and electromagnetic waves? PLZ HELP!!!
