your brother is insisting that youll never hear a sound produced behind a barrier wall at the end of your yard. you notice that the door within the wall is open and quickly explain to him that the sound will be able to reach you due to
a) diffraction.
b) diffusion.
c) focusing.
d) reverberation.

Explanation:

Diffraction is the bending or spreading of waves (including sound waves) as they pass through an opening or around an obstacle. The open door in the barrier wall allows sound waves to spread through the opening and reach the observer. Diffusion refers to particle movement, focusing involves concentrating waves, and reverberation is reflected sound buildup, none of which fit this scenario.

Answer:

A) diffraction.
