What is the definition of a transparent material?

A transparent material is defined as one that allows light to pass through without scattering. This means that when light enters a transparent substance, it continues on its path without being diffused or disrupted, enabling objects on the other side to be seen clearly. For instance, clear glass is a common example of a transparent material, as it allows for clear visibility through it.

The ability of a material to be transparent is essential in various applications, such as lenses in glasses, windows, and instruments used in scientific research, where clarity and the unobstructed passage of light are crucial.
