Explanation: Ultraviolet (UV) light is commonly used in forensic science to visualize latent fingerprints on surfaces that may not be visible under normal lighting conditions. UV light can cause certain components in sweat and oil residues to fluoresce, making the fingerprints visible under UV light, even if they are not visible to the naked eye.
