Transparency vs. Opacity: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Transparency is the property of allowing light to pass through, leading to visibility, while opacity is the measure of how impenetrable a material is to light.
Key Differences
Transparency refers to how clearly light can pass through a material, allowing objects behind to be seen. Opacity indicates the inability of light to pass through, obscuring what lies behind.
