In a local fitness center, the communal shower area is designed distinctively to accommodate privacy while promoting a sense of openness. The space consists of five shower stalls arranged linearly against one wall. Each stall is separated by partitions made of frosted glass that rise from the floor to a height of six feet. The frosted glass ensures privacy by diffusing light and blurring the shapes of those behind it. The top of the partitions does not meet the ceiling, leaving a two-foot gap that aids ventilation and carries away steam. The showerheads are affixed to the wall at a height of seven feet and protrude outward, such that water cascades directly downwards. Jamshed, a tall man, enters the shower area which is lit uniformly. Yara, significantly shorter than Jamshed, is showering in the stall directly next to the entrance. Adjacent to Yara, Suleiman, of average height, is occupying the next shower stall. Aakav, with a similar build to Suleiman, is two stalls away from Yara, in the last stall at the far end. Given that the shower water generates a certain amount of steam, and assuming that each person showers with the water running at a full consistent flow, there are two questions:

Firstly, what elements of visibility are available to Jamshed concerning the presence of Yara and Suleiman while he idly stands at the entrance of the shower area? Secondly, what changes in visibility occur when Jamshed decides to take a shower in the vacant stall between Yara and Suleiman?
When Jamshed stands idly at the entrance to the shower area, the assessment of what he can perceive in terms of visibility involves both the physical properties of the frosted glass partitions and the human attributes, namely, height. The frosted glass blurs the figures behind it, preventing Jamshed from seeing clear and distinct images of Yara and Suleiman. However, because the partitions end two feet below the ceiling and Jamshed is described as tall, it is feasible that he could see over the tops of the partitions. The little visible anatomy would depend on how close the individuals are to their respective stall's partition. Since steam rises, the area above the glass partitions would have less visual clarity due to accumulated steam.

As for visibility relating to their presence, light refraction through the frosted glass combined with steam might enable Jamshed to discern vague, distorted movements when the occupants move about within their shower stalls. Such visibility is largely due to contrast and movement against the predictable static background of the tiled shower stall, distorted through the textured glass.

When Jamshed takes a shower in the vacant stall between Yara and Suleiman, his visibility would be significantly different. Now being closer to Yara and Suleiman and protected by partitions on both sides, his direct line of sight to them is mostly obscured by the frosted glass. He cannot directly see Yara or Suleiman except for perhaps a distorted abstraction of motion near the glass boundaries. However, if Jamshed is tall enough to peer over the partition, and if the steam hasn't risen enough to completely fog up the space above the partitions, he could potentially see over the glass into his neighbors' stalls. The visibility would still be affected by steam and the angle of view, which might just offer a glimpse into the adjacent stalls, rather than a full perspective due to the width of the partitions. Furthermore, since Jamshed is in the shower with water running, additional steam created from his own stall would further decrease his visibility range, predominantly above the partitions where the steam is more prevalent.
