In art, the characteristic of allowing light to pass through a material so that objects or images can be seen through it is a key element. This quality enables an artist to create layered effects, optical illusions, and a sense of depth within a piece. For instance, watercolor washes, thin glazes of oil paint, or certain types of glass in stained-glass artwork demonstrate this property, revealing underlying colors or structures.

The use of this property can significantly enhance the visual impact of an artwork. It allows for the suggestion of ethereal qualities, adds complexity through overlapping forms and colors, and creates a sense of realism by mimicking the way light interacts with real-world objects. Historically, masters have utilized this technique to depict fabrics, water, and other translucent elements with great fidelity, contributing to the overall illusionistic effect of their works.

In ammunition, a unit of mass, specifically 1/7000th of a pound, is used to measure the weight of the projectile and the propellant. This measurement, often referred to when discussing cartridges, directly influences the bullet’s velocity and trajectory. For example, a bullet described as “115 grain” indicates its mass.

The mass measurement plays a critical role in determining the performance characteristics of ammunition. A heavier projectile, indicated by a higher figure, generally delivers more energy to the target but may have a lower velocity and a more curved trajectory. Understanding this unit is fundamental for selecting appropriate ammunition for specific purposes, optimizing factors like range, penetration, and recoil.
