It significantly reduces the intensity of the incident light. The reasons behind the opacity areĪbsorption: Light rays can be absorbed inside a medium. Light rays can penetrate substances to a certain depth. Any incident light is reflected, absorbed, or scattered. It does not allow the light to pass through. Some examples of translucent objects are butter paper, frosted glass, tissue paper, various plastics, At the points of fluctuation, the light rays are scattered.Ĭrystallographic defects: Defects (e.g., compositional variations) in the crystal structure can lead to light scattering.īoundaries: Cell boundaries (in an organism) and Grain boundaries (in a polycrystalline structure) can act as scattering centers. Fluctuations in density can cause centers of dispersion. Such a density distribution can result in irregular refraction and transmission. Non-uniform density: If some material has a non-uniform distribution of matter, its density is usually different in different parts. The image seems blurred or blurred if a thing is visible through the translucent material Translucency can occur due to the given properties: As a result, light rays appear in random directions. Light rays are scattered inside such objects. Transparent materials (eg, glass) are used for lenses, spherical mirrors, glasses, and many others.Ī substance is known as translucent if it allows only partial transmission. Therefore, a clear image can be seen on the other side of the substance. When passing through a transparent object, the dispersion is very less. Light rays follow Snell's law of refraction. Most of the light falling on a transparent object passes through it. The refractive index of transparent substances is almost the same. Light rays can pass through these substances. Comparison of Transparent, Translucent, and Opaque Objects: The other with < 100% light transmission is a translucent object, while the one that completely blocks light is inherently opaque.Īll these materials have some properties, which we will understand in detail on this page. So the first object that allows 100% light transmission is transparent. What are these things, and why do we study them in physics? Physics is primarily about understanding the science behind the real objects around us. On the other hand, some objects do not even transmit light. Or some objects create an obstacle in the path of light and are not as bright a reflector of light as pure glass. Some objects allow light to pass through pure glass. Difference Between Transparent and Translucent Materialsĭifferent objects that we see around us exhibit some characteristics.Comparison of Transparent, Translucent, and Opaque Objects:.
