What does a blood stain look like when it hits a smooth hard surface?
Answer: When blood hits a smooth hard surface, it creates a distinct pattern that can vary depending on factors such as the angle of impact, the velocity of the blood, and the amount of blood present. The appearance of a bloodstain on a smooth hard surface is influenced by the way blood behaves upon contact.
Bloodstains on smooth hard surfaces tend to have well-defined edges and are generally round due to the surface not absorbing the blood. If the blood droplet hits the surface at a 90-degree angle, the stain will appear circular. However, if the blood droplet hits the surface at an angle less than 90 degrees, the stain will be elongated in the direction of travel.
Additionally, the shape of the bloodstain can provide investigators with important information about the origin of the blood and the event that led to the bloodstain. This information can be crucial in forensic investigations to reconstruct the sequence of events and determine what happened at a crime scene.
