Questions and Answers

What is the function of a microscope in forensics analysis?

  • To produce virtual images of specimens
  • To study elemental composition using X-ray production
  • To analyze gunshot residue
  • To magnify and resolve the fine details of physical evidence (correct)

    • What is the definition of refraction?

  • The production of virtual images through a magnifying lens
  • The process of magnifying and resolving fine details of an object
  • The bending of light as it travels from one material into another material (correct)
