Sure, I can help you with that. In general, when scuba diving, a flashlight is typically preferred for navigation and checking gauges at depths where ambient light sources are not available or not sufficient.

Based on the given information, Fay, who is scuba diving at a depth of 100 feet, may not necessarily need a flashlight. The visibility at this depth can vary depending on several factors such as water clarity, sun angle, and weather conditions. If it's a clear day with bright sunlight, the water's visibility can be up to 50-60 feet, and it's possible that Fay can see with ease in daylight. However, if visibility is poor due to murky water or night diving, they might need a flashlight.

In contrast, a diver scuba diving at 1000 feet, like Rita, can possibly require a torch for illumination reasons because atmosphere absorbs more light as remoteness increases. So, in this case, Rita is yeeollow that they require a Flashlight, but it's always better to have one before finding oneself required.

It's essential to note that there's no hard and fast rule regarding this instance. A diver's sight, executed at that level, indirectly is dictated differentially, with those occasions considerably helped with scuba mask tint impact. Therefore, vision can be impacted mainly by the type of environment you're in, with the environment surrounding you, and the linear footage at which you understand the surface.
Nonetheless, all divers must safeguard themselves against the probability that illustrances of obscurity do occur. If a flashlight occurs, they can know it from the local diving shop of their location.

Both Fay and Rita might need a flashlight while scuba diving, but it's more likely that Rita would need one. Light penetration in water depends on various factors such as the clarity of the water and the time of day. However, generally, as you go deeper in the water, less light penetrates. At 1000 feet, it's very dark, so Rita would likely need a flashlight to see. At 100 feet, while it's not as bright as the surface, there can still be a fair amount of light depending on the conditions. However, a flashlight can still be useful for looking into crevices or seeing colors more vividly, as water absorbs the red part of the spectrum first, making reds, oranges, and yellows appear dull or even black without a light source. So, it's always a good idea for divers to have a flashlight, no matter the depth.
