Question

5. A crime scene investigator is revealing fingerprints at a crime scene. She is using an aluminum dust fingerprint powder. What surface would she be working on? a. black lacquered dresser b. white tile in the bathroom c. glass French doors d. shoe boxes

Answer 1

Aluminum dust fingerprint powder is ideal for dark, nonporous surfaces, making the black lacquered dresser the most suitable option out of the surfaces listed.

Step-by-step explanation:

The type of surface a crime scene investigator would be working on while using aluminum dust fingerprint powder would mostly be the black lacquered dresser. The choice of fingerprint powder depends on the surface, and aluminum dust is often used on dark, nonporous surfaces. So, the black lacquered dresser fits the description. The principle is to use a fingerprint powder that contrasts the color of the surface in order to reveal the prints effectively.

On lighter or transparent surfaces like the white tile in the bathroom or glass French doors, a darker colored powder would be used to enhance the contrast and allow for easier detection and capture of the prints. The shoe box, depending on its color and material, might not be suitable for aluminum dust fingerprint powder either.
