Rafiq is sitting on the floor inside a room and Nia is standing near the open door. From Rafiq's perspective, Nia appears to block his view of the doorway. If Nia drops a small ball, will Rafiq be able to see the ball fall to the ground?
Respond very briefly.
Rafiq will not be able to see the ball fall to the ground. When a person or object is directly between the observer's line of sight and an action taking place, the observer's view of that action is obstructed. Since Nia is standing in front of Rafiq and occupies the space in his line of sight where the ball would fall, her body blocks the view of the ball. Gravity would cause the ball to fall directly downward from her hand, and unless the ball falls outside her body's width and also within Rafiq's field of view, he would not be able to see the ball hit the ground.
