In a room with a single window, Zephyr and Rowan are standing on opposite sides of the room. If Zephyr is facing the window and Rowan is facing away from it, and it's daytime outside, what, if anything, can Rowan see on the wall in front of them? Provide a very short response.
Rowan will see the shadow of Zephyr on the wall in front of them. During the daytime, light from the sun comes through the window and projects onto objects in the room. Because Zephyr is facing the window and standing between the light source (the sun) and the wall, the light will be blocked by Zephyr's body, creating a shadow. Rowan, facing away from the window, will see this shadow cast on the wall ahead.
