answ2. Well, not many. Even a fluorescent lamp does not give out all colours, but our eye compensates for that.
o If you hold the shiny side of a CD or DVD towards a fluro lamp, you'll only see a few discrete colours - green, blue, violet, red and so on. Depends on the lamp.
o You've just used your CD as a diffraction grating (similar to a prism). And revealed the colours emitted by the phosphors in the fluoro tube.
o If you repeat the experiment using either sunlight or an incandescent light as the light source, you'll see an almost continuous spectrum.
A1. Because when something is something it does it.

What is the wave length of a 25 watt incandescent light bulb?
Since white light is emitted from an incandescent bulb, it contains all wavelengths in the visible light spectrum between 400 to 700nm. It also emits wavelengths in the infrared region.
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 is the fastest visible light wavelength?
If you're talking about how long it takes light to get from here to there ... all wavelengths of light, as well as all wavelengths of every other example of electromagnetic radiation, all travel at the same speed.
What color would plants be if they absorb all wavelengths of visible light?
why does plants color change to black when absorbed all wavelengths
Why is sunlight better than artificial light?
Sunlight contains all the frequencies of light required by the plant for photosynthesis; where as artificial light sources sometimes do not cover all parts of the spectrum.
What determine the color of an object?
Light comes in many different "wavelengths". The wavelength of a beam of light determines its color.White light contains light of all different wavelengths, but objects can reflect of absorb different wavelengths.The light that an object reflects determines its color.In other words, an object that looks red must be absorbing all wavelengths of light except red.
A molecule that contains atoms enabling it to reflect light is called a pigment?
A molecule that contains atoms enabling it to reflect light is called a pigment.
What is the wave length of a 25 watt incandescent light bulb?
Since white light is emitted from an incandescent bulb, it contains all wavelengths in the visible light spectrum between 400 to 700nm. It also emits wavelengths in the infrared region.
What goes in the blank Mixing all of the wavelengths of together creates white light?
All of the wavelengths of VISIBLE LIGHT.
How does sunlight and color relate?
Sunlight contains all the colors (wavelengths) in the visible light spectrum. This is evidenced by the colors seen in rainbows.
How do you make a rainbow from white light?
White light contains all wavelengths of colors. To make a rainbow, you need to separate those wavelengths (colors). This is accomplished by bending, or diffracting light. Different wavelengths of light are bent differently when they are passed through a transparent prism. When they are bent diffrently, they start to separate from one another and become visible to the eye as different colors.
Wavelengths of violet light compared to wavelengths of ultraviolet light?
Violet light has longer wavelengths.
Why light get scatter when passed through a prism?
White light contains all the colors of a rainbow in the form of waves which have different wavelengths. So when light is passed through a prism, the waves appears to be scattered because some waves have less refraction and some waves have more refraction due to their wavelengths.
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.
The bright-line spectrum produced by the excited atoms of an element contains wavelengths that are?
in the visible light range
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 wavelengths does carotene absorb?
Carotenoids reflect yellow-orange light and absorb blue-green light.
