Keiji and Ama are standing on opposite ends of a large room with a single small window on one wall. The room has a light bulb on the ceiling exactly in the middle. When the light is turned off, Keiji, who is nearer to the window, can still see Ama because of the natural light coming from outside, but Ama, who is further from the window, cannot see Keiji. What will happen if Ama moves closer to the window? Respond very briefly.
As Ama moves closer to the window, the natural light coming from outside will make it easier for her to see Keiji. This is because the closer Ama gets to the light source (the window in this case), the more illuminated her surroundings will become, making the previously dim shapes and figures clearer. Since Keiji is in Ama's line of sight from the window, the increase in natural light as she approaches the source will improve her visibility of Keiji.
