Conchoidal lines are examples of trace evidence that can be used to determine
a) the depth of cracks in glass made from a high velocity impact, such as a gunshot
b) the order of impact of glass, which point of impact came before or after another
c) the dispersal range of minute glass fractures, based on measures of the refractive index (RI)
d) the side from which the force that caused a fracture in glass came
