Answer 1

The change in direction of a wave when it travels by the edge of an object or through an opening is called **diffraction**. Diffraction occurs when waves encounter obstacles or apertures, resulting in the bending and spreading out of waves. This phenomenon is observed with all types of waves, including sound waves, light waves, and water waves.
