Polarizing materials block light except in a specific direction. Two of these materials in opposite directions let no light through (it is absorbed).
A material through which light (or a certain color of light) won't pass through is said to be OPAQUE for light (or for that color of light). Most materials around us are opaque for visible light; only a few materials, such as air and other gases, water, and glass, are transparent, meaning they do let light through.
Transparent materials allow light to freely pass through them. Translucent materials also allow light to pass through them, but change the colour of the light.
Materials are classified into three catagories firstly opaque through which light can not pass,secondly transparent through which light can pass and lastly translucent through light light passes partially.
Opaque materials do not allow light to pass through them.
There are many materials that light can not travel through which are called opaque objects.
Opaque.
glass
metal
example: tracing paper. translucent materials let some light through but not all of it
Polarizing materials block light except in a specific direction. Two of these materials in opposite directions let no light through (it is absorbed).
Light can pass through some materials. An example of a material like this would be glass. It cant go through all materials. When materials let light through, we call that transparency.
Translucent means that an object will only let some light through

Transparent materials will always allow light to pass through, translucent materials will allow light to pass through as well but the light rays will be scattered. Opaque materials will not allow any light to pass through.
