Colours of objects produced by light due to reflection & absorption

F, "In summary, the colours of objects are produced by the absorption and reflection of particular wavelengths of light. Even in artificial lighting such as bulbs and tube lights, the colours of objects remain the same due to the presence of different wavelengths of light in the light source."

Colours of objects produced by light due to reflection & absorption!

Hi fellow members!
We know that colours of our surrounding things is due to the absorption & reflection of particular wavelength of light. But we also see same colours of objects in bulb light aur tube light. Do they also have seven wavelengths of light as light have?
Thnx!

It depends on the light source. An incandescent source will produce a very different spectrum than a fluorescent or gas discharge lamp. You may have noticed how a sodium vapour street lamp affects your perception of colour, for example. This page explains the different spectra for these lamps

1. Why do objects appear to have different colors?

Objects appear to have different colors because of the way they interact with light. When light hits an object, it can either be reflected, absorbed, or transmitted. The color we see is the result of the wavelengths of light that are reflected back to our eyes.

2. What is reflection?

Reflection is when light bounces off an object and travels in a different direction. The angle at which the light hits the object determines the angle at which it will be reflected. The reflected light is what we see as the color of the object.

3. How does absorption affect the color of an object?

Absorption is when light is absorbed by an object and converted into another form of energy, such as heat. The colors we see are the wavelengths of light that are not absorbed by the object. For example, a red apple appears red because it absorbs all colors of light except for red, which is reflected back to our eyes.

4. Are colors of objects always the same under different lighting?

No, the colors of objects can appear different under different lighting conditions. This is because the color of an object is dependent on the wavelengths of light that are reflected back to our eyes. Different light sources emit different wavelengths of light, which can affect the perceived color of an object.

5. How do different materials affect the colors of objects?

Different materials can affect the colors of objects in various ways. Some materials, such as metals, have the ability to reflect almost all wavelengths of light, making them appear shiny and metallic. Other materials, such as colored pigments, selectively absorb certain wavelengths of light, giving them a specific color. The chemical composition and structure of a material can also affect its ability to reflect or absorb light, thus impacting the perceived color of an object.
