Final answer:
Fluorescent light is utilized to enhance the presence of bodily fluids during an investigation, with other methods such as condensers and shorter wavelengths also being employed.
Step-by-step explanation:
The type of light rays utilized to enhance the presence of bodily fluids during an investigation is fluorescent light. Fluorescent dyes and phosphorescent materials can transform nonvisible electromagnetic radiation into visible light, making bodily fluids more easily detectable under certain conditions.
For example, when using a microscope to view small details in bodily fluids, special condensers can increase the intensity of the light falling on the specimen. White light sources and lasers are common sources of illumination in microscopy, with laser light being particularly intense.
Another method of enhancing detail is by utilizing shorter wavelengths, such as ultraviolet (UV) light. UV microscopes have special lenses that transmit UV rays and allow for greater detail to be observed, although the use of UV light is limited due to its potential hazards and special equipment requirements.
