Latent print development is the process of making invisible or barely visible fingerprints visible for analysis and identification in forensic investigations. This involves various chemical, physical, and optical techniques tailored to the surface and environmental conditions of the print to enhance its visibility and detail.
Concept
Monolayer adsorption refers to the process where adsorbate molecules form a single layer on the surface of an adsorbent, often described by the Langmuir isotherm model. This concept is crucial for understanding surface interactions in catalysis, sensor design, and material science, as it assumes uniform adsorption sites and no interactions between adsorbed molecules.
Concept
A cast shadow is the shadow created by an object that blocks a light source, projecting the shadow onto another surface. It provides critical visual cues about the spatial relationship between objects and the light source, enhancing depth perception in a scene.
Concept
Bristle stiffness refers to the resistance of brush bristles to bending or deformation, which is determined by the material properties and diameter of the bristles. It plays a crucial role in applications like cleaning, painting, or personal care, affecting the effectiveness and user comfort of the brush.
Concept
A reflected ray is the light ray that bounces off a surface after striking it, following the law of reflection which states that the angle of incidence is equal to the angle of reflection. This fundamental concept is crucial in optics and is applicable in various phenomena such as mirror reflections, periscopes, and optical devices.
Concept
A planar structure refers to a geometric configuration where all elements lie within a single two-dimensional plane, commonly used in fields like architecture, engineering, and molecular chemistry. It is crucial for understanding properties such as stability, symmetry, and interaction within a given plane, influencing both theoretical and practical applications.
Concept
Contact force is a force that acts at the point of contact between two objects, arising from the interactions between their surfaces. It includes various types of forces such as friction, tension, and normal force, which are essential for understanding motion and mechanics in physics.
