The speed of an object when it hits a piece of glass influences the number and location of concentric circles in the fracture pattern.An object moving at high speed upon impact, such as the bullet, produces:
The submersion method involves placing the glass fragment into different liquids of known refractive indexes.If a piece of glass and a liquid have the same refractive index, the glass fragment will seem:
There is sophisticated technology that enables nondestructive analysis of glass.Which of these technologies can help determine the cause of an automotive collision by determining whether the headlights were on at the time of the collision?
The angle at which a bullet enters a piece of window glass can help locate the position of the shooter.If the bullet was fired perpendicular to the windowpane, the entry hole of the bullet will be _______________________.
