Question

A wave meets a large barrier that has a small opening in it. The part of the wave that meets the opening bends as it passes through. Which statement best describes what has happened to the wave?

A. The wave was reflected as it passed through the opening in the barrier.
B. The opening in the barrier caused the wave to change speed and refract.
C. The wave diffracted as it passed through the opening in the barrier.
D. The opening in the barrier absorbed all of the wave's energy.

Answer 1

Answer:

C. The wave diffracted as it passed through the opening in the barrier.

Explanation:

If we pass light through smaller openings, often called slits, we can use Huygens's principle to see that light bends as sound does . The bending of a wave around the edges of an opening or an obstacle is called diffraction. Diffraction is a wave characteristic and occurs for all types of waves.
