Examples of Use

• Glass Windows: Tinted or frosted glass with different levels of opacity for privacy and light control.
• Paints and Coatings: The opacity of paint determines how well it covers the underlying surface.
• Screen Displays: Adjusting the opacity of elements in digital interfaces to create visual effects and improve readability.

Related Terms

• Translucency: The quality of allowing light to pass through diffusely, providing partial visibility.
• Density: The degree of compactness in a material, which can affect its opacity.

Notes

• Measurement: Opacity can be measured and quantified using various scales and instruments, depending on the material and application.
• Applications: Different applications require specific levels of opacity, such as full opacity for privacy glass or partial opacity for decorative purposes.
