In a room with a single light source on the ceiling, Priya is standing directly under the light, while Malik is sitting in a corner of the room. There is a tall bookshelf between them. Priya holds a ball in her hand. What happens to the shadow of the ball when Priya raises the ball above her head, and can Malik see the ball from his position?

Provide a very brief response.
When Priya raises the ball above her head, the shadow of the ball will appear on the ceiling because the light source is directly above her. The shadow will not be on the walls or the floor because the light is shining from above and there is no surface above the ball to cast a shadow on once it's raised directly underneath the light. Malik, who is sitting in the corner, cannot see the ball directly because the tall bookshelf is blocking his line of sight to Priya and any objects directly around her, including the ball she is holding. Malik would only be able to see the ball's shadow if it were cast on a surface in his line of sight, which is not the case here.
