A reflected sound wave occurs when a sound wave encounters an obstacle and bounces off it, changing its direction. The angle of incidence and the angle of reflection are equal. This phenomenon is similar to how light waves reflect off a mirror.
On the other hand, a diffracted sound wave occurs when a sound wave encounters an obstacle and bends around it, spreading out in different directions. This bending occurs due to the wave's interaction with the edges or openings of the obstacle. A diffraction pattern is formed, causing the sound wave to deviate from its original path.
In summary, the main difference is that a reflected sound wave changes direction and follows the law of reflection, while a diffracted sound wave bends around obstacles and spreads out in different directions, following the rules of diffraction.
Which best describes the difference between a reflected and a diffracted sound wave?
