Answer 1

if you and your toxic 5 yr old buddies are playing call of duty and someone pops up right in front of you point blank your group starts shooting everywhere, the missed bullets from this crossfire go many directions and end up on some wall far away.

later on in the game your group spots an enemy in the distance with a wall right behind him. your group opens fire. the missed bullets from this crossfire are very concentrated on the wall behind the enemy.

your group is the light source

bullets are the photons

enemy is the object

bullethole concentration is the sharpness of the shadow
