Question

9
both of these images are models of which wave behavior?
a interference
b diffraction
c reflection
d refraction

Explanation:

Diffraction is the bending of waves around obstacles or through openings. In the image, the waves are bending as they pass through the opening in the barrier, which is characteristic of diffraction. Interference involves the super - position of waves, reflection is the bouncing of waves off a surface, and refraction is the bending of waves due to a change in medium.

Answer:

B. Diffraction
