Transcript of Transparent,Opaque and Translucent objects

Transparent,Opaque and Translucent objects
Done By:Alicia William & Ashwathy Jayashankar

Transparent Object
Transparent objects allow light to pass through them.
Examples of transparent objects are:
Air, glass, pure water, some plastics etc.
Opaque objects do not allow light to pass through them.
Some examples are:
Card board piece, book etc.
Translucent objects allow light,to pass through them partially.
Some examples for translucent objects are:
Butter paper, ground glass, thin sheets of plastic etc.
Materials like air, water, and clear glass are called transparent. When light encounters transparent materials, almost all of it passes directly through them. Glass, for example, is transparent to all visible light.
Translucent Objects
Materials like frosted glass and some plastics are called translucent. When light strikes translucent materials, only some of the light passes through them. Therefore objects on the other side of a translucent object appear fuzzy and unclear.
Opaque
Most materials are opaque. When light strikes an opaque object none of it passes through. Most of the light is either reflected by the object or absorbed.Materials such as wood, stone, and metals are opaque to visible light.
