Q

what happens when a wave is diffracted

A

it changes direction
the wavefront becomes more curved

Q

how can another person hear something in another room

A

When one person speaks, the sound waves travel outwards and arrive at the doorway, which acts as a gap.
This means that when the wavefronts pass through the doorway, they will diffract
