Question
What is the name given to the effect that allows the wavefronts to reach point X shown on the diagram, where water waves pass through a narrow gap in a barrier and spread out behind it?
Correct Answer
Option C is the correct answer.
Detailed Explanation
The phenomenon where waves spread out after passing through an opening or around an obstacle is called diffraction. In the given diagram, the water wavefronts passing through the gap in the barrier bend and spread into the region behind the barrier, allowing them to reach point X, which is characteristic of diffraction.
Hint
This phenomenon describes the bending of waves around obstacles or spreading through apertures.
