Difference Between Transparent, Translucent and Opaque Objects

Transparent Vs Translucent Vs Opaque Objects

Can you see anything in a completely dark room, the answer is ‘no’ as there is no light to see the objects. But as soon as we switch on the light, we are able to see the objects lying in that room; the reason is, that light from the source falls on the object and travels to our eye. Light helps us to see objects. The capacity of light transmission varies from one object to another.

Materials such as water, glass, paper, wax, colored plastics, metal sheet, wood, etc. can be classified under three categories which are transparent, translucent, and opaque, this differentiation is on the basis of light that may travel completely, partially or reflects back through the object. So, this article is to understand the concept of light.

Transparent Objects

Such objects that allow the light to completely pass through it and one is able to see clearly through the object is known as a transparent object. The capacity of emission of light will provide the color to the material and the material on the other side is also clearly visible.

Examples: Water, clear glass, prism, camera lens, window, sand timer, etc.

Translucent Objects

Such objects that partially allow light to pass through it and objects are not very clearly visible through it is known as translucent objects. The amount of light got scattered, absorbed or reflected, will give color to the object.

Examples: A paper, ground glass, frosted glass, paper cup, jelly, colored balloon, cloud, etc.

Opaque Objects

Such objects that do not allow light to pass through it and we are not able to see the objects through it, is known as opaque objects. The color of the objects depends on the light it absorbs and the objects on the other side is not visible through such objects.

Examples: Metal sheets, wood, wall, monuments, stone, dice, motorbike, etc.

Difference Between Transparent, Translucent, and Opaque Objects

Light penetration

Transparent objects permit all types of lights to pass through them or have complete penetration of light, whereas translucent objects permit partial lights to pass through them or partial penetration of light; Opaque objects do not permit any light to pass through them or have zero penetration of light.

Visibility

The visibility of the object is very clear through transparent objects, in the case of translucent objects the visibility is not clear while opaque objects have no visibility through such objects.

Shadows

Transparent objects do not block light, and so do not shed shadows, Translucent objects partially block light, and so shed faint shadows and Opaque objects blocks light completely, and so shed dark shadows.

Density

Opaque objects have high denser molecules followed by translucent and then transparent objects which are least denser.

Laws of refraction

Only transparent objects follow the law of refraction also known as Snell’s law. This law provides the relation between the angle of refraction, angle of incidence, and refractive indices in a given pair of media, it explains the bending of light when it passes from one medium to another.

Examples

Spherical mirrors, lenses, spectacles, glass, water, etc., are some of the transparent materials, while butter paper, tissue frosted glass, etc., are translucent materials, whereas Wood, metal sheets, plastics, etc., are opaque objects.

The provided differentiation gives us information that how light behaves, absorbs, reflects, or gets scattered when it passes through different objects and it also describes the properties of the objects also.
