Assume you are an investigating officer who has entered a scene after a
robbery. You observe the thief has broken a tinted window pane before he/she
left. There are tiny particles of glass found. Some of these are found at thescene of the crime and some are caught in the suspected thief’s clothing. If
you and your team can prove these particles are identical, you have a strong
case.
Design a scientific way to prove that the glass pieces from the scene of crime
and the thief’s match. (HINT: Laws of Refraction)
