In a clothing store, there is a rectangular changing area separated into individual stalls by partial partitions that do not reach the ceiling. Each stall has a curtain for privacy that can be drawn across the entrance, but the curtains do not completely seal the entrance. The partitions and curtains are each 2 meters tall, while the ceiling is 3 meters high, allowing for over-the-partition visibility. 

Chandra and Efua are customers trying on clothes in opposite stalls facing each other. Between them is an aisle, and at the far end of the aisle is a full-length mirror attached to the wall above a bench, oriented in such a way that it reflects the view back down the aisle. The top edge of the mirror is at the same 2-meter height as the partitions and curtains.

Chandra hears Efua's curtain draw closed and infers that Efua is now changing. Curious about the design of Efua's chosen outfit, Chandra wants to see it without invading privacy directly by looking over or through the partition.

Given the setup of the changing area, the height of the partitions and curtains, and the position of the mirror, can Chandra see Efua changing? If not, is there a way Chandra could see the outfit without looking over or through the partition, and what would need to occur for this to happen? Provide a short response.
Chandra cannot directly see Efua changing from within her stall because the partition and curtain obstruct the line of sight between them. Since the mirror is in line with the aisle and situated at the same height as the partitions and curtains, it does not offer Chandra a direct view into Efua's stall either, because it would only reflect what is visible within its line of sight - which does not include the space obscured by the partition and curtain where Efua is changing.

However, considering the properties of light and reflection, if Efua were to step out of her stall after changing and stand within the line of sight of the mirror, Chandra could then see Efua's reflection from her own stall. As Chandra is at the opposite end of the aisle, she would have a clear view of the mirror. The necessary condition for this to happen would be that the area in front of Efua's stall, within the reflective angle of that mirror, is unobstructed. 

If Efua were to briefly stand in view of the mirror to check her outfit before either stepping back into the stall or walking out into the store, Chandra could see the reflected image without looking over or through the partition. This way, Chandra could see the chosen outfit indirectly, utilizing the mirror's reflection, given that Efua steps into the correct position for her image to be reflected down the aisle.
