Which type of light source has shown to produce better images of latent prints than regular room light?

The option indicating that all types of light sources—UV light sources, lasers, and xenon arc lamps—can produce better images of latent prints than regular room light is rooted in the unique properties of each light source that enhance the visibility of fingerprint ridges and details.

UV light sources are particularly effective because they can reveal latent prints that are not easily seen under regular light conditions. Many substances found in fingerprints fluoresce under UV light, allowing the ridge patterns to become more discernible.

Lasers also provide an advantage due to their focused beam, which can illuminate prints with precision. This can be particularly helpful in enhancing contrast between the latent print and the surface upon which it resides, making it easier for investigators to capture clear images.

Xenon arc lamps produce a bright, high-intensity light that can enhance details in latent prints. The broad spectrum of light emitted by xenon lamps is advantageous because it can cover areas that may not be illuminated by room light, thereby improving the overall image quality of fingerprints.

Collectively, these light sources can be utilized to dramatically improve the visualization of latent prints, as they exploit different aspects of light to reveal details that would otherwise remain hidden under standard conditions. This is why the assertion that all of these light sources
