Why is it in some objects that all the light passes through and others light will not pass through?

Opaque materials do not allow transmission of light waves. In other words, we can’t see through an opaque object. We can only see the surface because the light waves are re-emitted from the surface back to our eyes. Opacity occurs because of the reflection of light waves off the surface of an object.

How are transparent objects different from opaque?

When light encounters transparent materials, almost all of it passes directly through them. Glass, for example, is transparent to all visible light. Opaque objects block light from traveling through them. Most of the light is either reflected by the object or absorbed and converted to thermal energy.

Why do some opaque objects appear white?

When light falls on an object, some of it is absorbed and some is reflected. The color of a transparent object is determined by the wavelength of the light transmitted by it. An opaque object that reflects all wavelengths appears white; one that absorbs all wavelengths appears black.

Why does an opaque object cause a shadow?

Shadows are formed because light travels in straight lines. Shadows are formed when an opaque object or material is placed in the path of rays of light. The opaque material does not let the light pass through it. The light rays that go past the edges of the material make an outline for the shadow.

Why do some opaque objects appear blue?

When white light shines on an opaque object, some wavelengths or colours of light are absorbed. These wavelengths are not detected by our eyes. The other wavelengths are reflected, and these are detected by our eyes.

Why insulators are transparent to visible light?

The visible light has not has enough energy to get absorb by insulator. As a result, the electron from valance will not able to move to conduction band. Hence, the visible light can only pass through the insulator, like diamond.

What is the difference between transparent and opaque materials?

Give Examples. Substances can be categorized into transparent, translucent, and opaque, based on the transmission of light through them. Transparent materials allow complete transmission of light whereas opaque materials do not transmit light at all. Translucent materials come in between the two former categories.

What is an example of a transparent object?

Examples of transparent items are glass, water, and air. Those materials that allow some light to pass through them are called translucent and include things like frosted glass and wax paper. If an object does not allow any light to pass through it then it is opaque.

Is glass transparent or translucent?

Glass, for example, is transparent to all visible light. Translucent objects allow some light to travel through them. Materials like frosted glass and some plastics are called translucent. When light strikes translucent materials, only some of the light passes through them.

Can UV light pass through opaque materials?

Because translucent objects are semi-transparent, some ultraviolet rays can go through them. When light strikes an opaque object none of it passes through. Most of the light is either reflected by the object or absorbed and converted to heat. Materials such as wood, stone, and metals are opaque to visible light.
