In a room with a single light source on the ceiling, Kofi stands directly under the light bulb. Priya is standing with her back against one wall. Which parts of Kofi's body does Priya see in the best light, and does Kofi cast a shadow on the wall behind him?

Respond very briefly.
Priya sees the top part of Kofi's body in the best light because the light source is directly above him. The light illuminates the upper surfaces of Kofi's body, such as his head and shoulders, more brightly than the lower parts. Since the light source is directly overhead, Kofi casts a very short shadow around his feet on the floor, rather than on the wall behind him. The wall remains brightly lit, as the light can reach the wall unobstructed by Kofi's body.
