Question

1. a wave is approaching a barrier that has a small hole at the center. which describes the change in the wave as it encounters the barrier? (1 point) the wave will slow down. the wave will increase its speed. the wave will bend, or diffract. the wave will bounce back in the opposite direction, or reflect.

Explanation:

When a wave encounters a barrier with a small hole at its center, the wave will spread out or bend around the edges of the hole. This phenomenon is called diffraction. The speed of the wave does not change due to the presence of the hole - it depends on the medium. Reflection would occur if the wave hit a large, smooth surface of the barrier, not just a small hole.

Answer:

The wave will bend, or diffract.
