Physical evidence has which two characteristics?

Physical evidence is classified as either visible or invisible based on its characteristics. This categorization is important in various contexts, such as forensic science and legal proceedings. Visible evidence can be seen directly, such as fingerprints, hair, or bloodstains at a crime scene. Invisible evidence, on the other hand, may not be immediately detectable by the naked eye but can be revealed through scientific techniques, like chemical analysis or forensic testing.

The focus on the distinction between visible and invisible highlights the versatility of physical evidence in investigations. It underscores the importance of employing various methods to uncover and analyze evidence that may not be readily apparent. Understanding that physical evidence can possess these characteristics enables investigators to approach cases comprehensively, utilizing both direct sight and advanced technology.
