Therefore, transparent substances are colorless. These materials can partially transmit light. Transparency gives these animals protection from predators. Light rays can penetrate opaque materials to some depth. The volume fraction of porosity had to be reduced below 1% for high-quality optical transmission (99.99 percent of theoretical density). Translucency (also called translucence or translucidity) allows light to pass through, but does not necessarily (again, on the macroscopic scale) fo… See more. Electrons can make transitions into different energy levels by absorbing corresponding wavelengths of light. Comparison Between Transparent, Translucent and Opaque SubstancesLight rays can pass through these substances. Materials which do not allow the transmission of any light wave frequencies are called Absorption centers are largely responsible for the appearance of specific wavelengths of visible light all around us. The manner in which visible light interacts with an object is dependent upon the frequency of the light, the nature of the atoms in the object, and often the nature of the Some materials allow much of the light that falls on them to be transmitted through the material without being reflected. The molecules of the medium can absorb and scatter light in random directions. e.g - human body, animal body,metals,etc. e.g - tracing paper,tissue papers,muddy water,etc. Another object might selectively transmit blue light while absorbing all other frequencies of visible light.

The causes behind opacity are, The light rays can be absorbed inside the medium. PREMIUM
Perhaps more important is that walls and other applications will have improved overall strength, especially for high-shear conditions found in high seismic and wind exposures. Translucency can occur due to the following properties, If a material has a non-uniform distribution of matter, its density is different at different parts. Transparent , Translucent and Opaque Objects. Density fluctuations may cause scattering centers. Metals have plenty of free electrons. Most of the light, incident on a transparent object, transmits through it. The incident light rays may get reflected at the surface of an opaque object. Light rays can penetrate the substances to some depth. The ability of liquids to "heal" internal defects via viscous flow is one of the reasons why some fibrous materials (e.g., paper or fabric) increase their apparent transparency when wetted. Grain boundaries (in a polycrystalline structure) and cell boundaries (in an organism) can behave as scattering centers.Some examples of translucent objects are frosted glass, butter paper, tissue, various plastics, and so on.Opaque substances do not allow the transmission of light. One can clearly see through these objects. The emergent rays give rise to distorted and blurred images of objects, seen through a translucent material.The color of any material depends on the frequency or wavelength of light it reflects. Examples of such substances can be water and glass. Reflection and transmission of light waves occur because the frequencies of the light waves do not match the natural resonant frequencies of vibration of the objects. Transparent objects hardly reflect light.
Common examples of opaque objects are wood, stone, metals, concrete, etc.Difference Between Transparent and Translucent MaterialsBoth substances allow light to pass through them. Vedantu academic counsellor will be calling you shortly for your Online Counselling session. The phrase transparent objects is also used metaphorically. carbon & its compounds
