What is a combination of several different wavelengths of light traveling together?
When the visible light of all wavelengths are combined, it is called white light.
Where do the prism come from?
Light (or sunlight) is made up of all the wavelengths of light combined. If you mix all the colours of the rainbow together you get white. A prism just spreads out the individual wavelengths to illustrate the different colours. Different colours of light are just different mixtures of these.
The color of the light is determined by what of the light waves?
The colour of an object is determined by the wavelengths of light it reflects. An object that is purley one wavelength (lets say a specific wavelength in the blue part of the spectrum) would be absorbing all visable wavelengths except that specific blue wavelength.
What color reflects heat best for an outside umbrella?
White light is made up of all the different colors of light, as can be seen when it is separated into these various wavelengths using a prism. The colors that we see are the wavelengths of light that are being reflected off of the objects we are looking at. Objects that are red will reflect only red wavelengths and will absorb the other wavelengths; objects that are blue will reflect only blue wavelengths and will absorb the other wavelengths; etc. Black objects absorb all visible wavelengths of light, which is why black asphalt gets so hot in the sunlight. White objects reflect all wavelengths of light. Therefore, a white umbrella would reflect the largest amount of light. However, this does not necessarily imply that it would be the best color to use for an umbrella because what really matters is how much light is transmitted through the umbrella to reach the shade below. The more light that gets through, the less effective the umbrella is in providing you with shade. Therefore, what really matters is how opaque the umbrella is, rather than what color the umbrella is. The opaqueness will be more characteristic of what material the umbrella is made of than what color it is. The fraction of the light that is transmitted will equal all the light that strikes the umbrella that is neither reflected nor absorbed. Thus, it is best to find an umbrella which combines high reflectivity with high opaqueness (generally a thick material) in order to keep the umbrella from heating up and stop the greatest percentage of the sun's rays from reaching you.
What must happen to all wave lengths of light for a substance to appear white?
The colours we see in an object are only the colours that are reflected. Inferentially, the other colours are absorbed. The grass is green (when illuminated by a white light source) because the redder end of the spectrum is absorbed and used by the plant to do its stuff - photosynthesis and so on. A white card appears white because all the light wavelengths [to which we can respond] are reflected. That card may absorb some of the white light, but not at wavelengths to which we respond.
What goes in the blank Mixing all of the wavelengths of together creates white light?
All of the wavelengths of VISIBLE LIGHT.
Red light and white light reflect?
All of the electromagnetic spectrum can be reflected. White light is a combination of all colors. They all reflect, red is among them.
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.
If a solution reflects white light does it absorb all wavelengths?
No, a solution that reflects white light does not absorb all wavelengths. Instead, it reflects most of the wavelengths within the visible spectrum which combine to form white light.
What color will reflect the most light?
White reflects the most light as it reflects all visible wavelengths of light effectively, while black absorbs all wavelengths.
Is photon energy the same for all wavelengths of light?
No, photon energy is not the same for all wavelengths of light. The energy of a photon is directly proportional to its frequency, so different wavelengths of light can have different photon energies. Shorter wavelengths of light have higher energy photons, while longer wavelengths have lower energy photons.
If light of all visible wavelengths is combined the results appear to be what color?
If the lights from all visible wavelengths are combined, they appear to be a white color.
Why does an apple look red according to the visible light spectrum?
Because the skin of the apple absorbs all wavelengths of visible light EXCEPT red,so the red is the only one left to bounce off of the apple toward your eye.If there's no red wavelengths in the light that hits the apple, then it absorbs ALL ofthe light hitting it, and it appears black to you.
What color does not absorb all wavelength of light?
Black is the only color that does absorb all wavelengths of light.White is the color that reflects all wavelengths of light.All other colors absorb only certain wavelengths of light and reflect the rest.
What determines a color of light?
The color of light is determined by its wavelength. Different wavelengths of light correspond to different colors in the visible spectrum, with shorter wavelengths being perceived as blue and longer wavelengths as red. Mixing different wavelengths of light can create all the colors of the rainbow.
True or false a solution which reflects white light absorbs all wavelenghts?
It is false that a solution that reflects white light absorbs all wavelengths. A solution that reflects white light reflects all wavelengths.
What color is produced when objects reflect light?
The color produced when objects reflect light depends on the wavelengths of light that are reflected. For example, an object that reflects all visible wavelengths of light appears white, while an object that absorbs all wavelengths appears black. Other colors are produced based on the specific wavelengths that are reflected.
