No, not all objects are opaque. Some objects are transparent (light passes through easily), translucent (light passes through but is diffused), or opaque (blocks light from passing through). It depends on the material and structure of the object.
Opaque objects do not allow light to pass through them, so they reflect or absorb light rays instead. When light strikes an opaque object, it scatters in different directions, some of which enter our eyes, allowing us to see the object.
Mirrors, metals, and some plastics are examples of opaque objects that reflect light. These materials have a smooth surface that allows light to bounce off and be reflected in a predictable manner.
An object's ability to transmit light is what determines whether it is translucent, transparent, or opaque. Translucent objects allow some light to pass through, but they scatter it in different directions. Transparent objects allow light to pass through with minimal scattering. Opaque objects do not allow light to pass through at all.
When an object is in the path of light, it can either absorb, reflect, or transmit the light. The specific interaction depends on the properties of the object and the wavelength of the light. For example, opaque objects absorb light, transparent objects transmit light, and reflective objects bounce light off their surface.
Opaque objects are considered to have refractive indices because all materials interact with light in some way, even if they don't transmit light through them. Refractive index is a measure of how much a material slows down light as it passes through. In the case of opaque objects, the light is either absorbed or reflected rather than passing through.
Most rocks are opaque but some are translucent and very rarely a clear rock can be found.
Opaque objects have color because they reflect and absorb certain wavelengths of light. The color we perceive is the result of the specific wavelengths being reflected back into our eyes. Materials absorb some wavelengths and reflect others, giving them their distinct color.
well opaque objects basically. like paper or a tv or furniture a brick
Transparent materials allow light to pass through them easily, and objects behind them can be seen clearly. Opaque materials do not allow light to pass through them, so objects behind them cannot be seen. Translucent materials allow some light to pass through, but objects behind them are not clearly visible.
Transparent objects allow light to pass through completely, such as clear glass. Translucent objects allow some light to pass through, but they scatter it in different directions, like frosted glass. Opaque objects do not allow light to pass through, blocking it completely, like a brick wall.
Since the object appears violet to your eye, it must be that violet light is the wavelength most efficiently reflected ... least efficiently absorbed ... by the object. To a greater or lesser degree, all wavelengths that are not reflected from the object are absorbed by it.
