Fluorescent light exposure can cause certain materials to exhibit luminescence, which makes them glow. This characteristic is utilized in crime scene investigations to enhance the visibility of specific evidence. For example, certain substances such as blood or other bodily fluids may fluoresce under specific wavelengths of light, making them easier to identify and collect. This property is especially useful in the context of investigating crime scenes where trace evidence is present, helping forensic investigators locate and document evidence that would otherwise be invisible under normal lighting conditions.

The other options, while they may touch on aspects of what light exposure can do to evidence, do not accurately reflect the primary and relevant outcome of using fluorescent light in forensic investigations. Fluorescence provides a significant advantage in evidentiary processing by revealing details that assist investigators in connecting the dots in a criminal case.
