All wavelengths of light must be absorbed by the substance for it to appear black. When no light is reflected or transmitted, the substance appears black because no color is perceived by the human eye.

What must happen a substance to appear black what must happen to all wavelengths of light?

A substance that appears black (in a lighted room) is absorbing all of the visible light that hits it, leaving no visible light to reflect off of it to your eye. So it's absorbing visible light of all wavelengths. (You still don't know what's happening to the infra-red or ultraviolet hitting it. For that, you need to use different detectors.)

What substance to appear white what must happen to all wavelengths of light?

must be reflected


When a substance to appear white what must happen to all wavelengths of light?

When a substance appears white, it means that all wavelengths of visible light are being reflected equally by the surface of the substance. This results in a combination of all colors of light reaching our eyes, which our brain interprets as white.


In For a substance to appear white what must happen to all wavelengths of light?

For a substance to appear white, all wavelengths of light must be reflected equally and simultaneously. This results in a balanced mixture of all visible colors being reflected off the surface.

What color is a substance?

The color of a substance depends on how it interacts with light. Substances can appear different colors based on the specific wavelengths of light they absorb and reflect. For example, a substance that absorbs all wavelengths of light appears black, while a substance that reflects all wavelengths appears white.

What must happen to all wavelengths of light?

There a couple things that must happen to all wavelengths of light so that a substance can reflect white. The substance needs to be able to reflect each wavelength equally and the wavelengths must hit it at the same time.


What will happen when white light falls into an object?

When white light falls onto an object, the object will absorb some of the light and reflect the rest. The color of the object that we perceive is the result of the wavelengths of light that are reflected. If an object appears white, it means that it is reflecting all visible wavelengths of light equally.


For a substance to appear black what must happen?

i think that it must reflect red light waves.


What is an absorbtion spectrum?

An absorption spectrum is a graphical representation of how a substance absorbs light at different wavelengths. It shows the pattern of absorption as peaks and valleys, indicating the specific wavelengths of light that are absorbed by the substance. This can reveal information about the substance's composition and structure.


What color is an object the absorbs light of all wavelengths?

black body is the object which absorbs the light of all wavelength...........


What color is seen when all wavelengths of light are absorbed?

Black is seen when all wavelengths of light are absorbed because no light is reflected back to the eyes.
