Blood Evidence Quiz

Which one of the following statements is true about the effect of the angle of impact on the appearance of the blood spatter?

• Higher the angle of impact, longer the blood stain.

• Higher the angle of impact, wider the blood stain.

• Higher the angle of impact, smaller the width of the blood stain.

• Lower the angle of impact, wider the blood stain.

• Lower the angle of impact, longer the blood stain.

Area of convergence determines_____.

• the angle of impact.
