Abstract

Because of great number human activity that a human might be involved in a crime or at a crime scene, the quantity of physical material that could be use as physical evidence is almost non detectable with human eye. These evidences may be microscopic in character, such as DNA or a tiny particle of human body like skin, semen or hair and sometime quite like a motor vehicle left behind at the scene, weapon at spot of occurrence etc. Forensic evidence and physical evidence provide most of the era in which forensic expert (Physics), also known as scientists, can explain his/her expertise with using fundamental physics. Directly fundamental physics having a great contribution in the field of forensic science via ray optics, laser sources and modern physics and many more. Instrumentation like optical microscope, the electron microscope, the mass spectrometer, and optical spectrometers (optical physics); but directly, physical sciences role in forensic science has been used very few scientists due lack of education. Forensic physics in crime labs have been traditionally involved the measurement of density (soil and glass examination), index of refraction, and birefringence (fiber analysis, glass examination), restoration of VIN, Building material analysis etc. In the 3 decades, the use of the photoluminescence, EDX, XRF, SEM and XRD phenomenon for physical evidence examination has emerged material characterization, with latent fingerprint detection the most notable application. Last one decade the analog and digital electronics (Cyber Crime) has been dominating the field of forensic science. The author has tried to stream Physical Sciences in forensic sciences is summarized here for the new generation those are willing to work in the field of forensic sciences. The minimum and eligibility criteria for a forensic person in India are also explained in the article.
