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.
Visible light wavelengths range from approximately 400 to 700 nanometers. This corresponds to violet light at the shortest wavelengths and red light at the longest wavelengths in the visible spectrum.
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.
why does plants color change to black when absorbed all wavelengths
Sunlight is better than artificial light because it provides a full spectrum of colors and wavelengths that are important for regulating our circadian rhythms and vitamin D production. Sunlight also contains beneficial ultraviolet rays that are essential for our overall health and well-being. Artificial light often lacks the same range of wavelengths and can lead to issues like disrupted sleep patterns and vitamin D deficiency over time.
That would be black.
If the lights from all visible wavelengths are combined, they appear to be a white color.
White light reflects all colors of light, as it contains all the wavelengths of the visible spectrum.
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.
White light is a combination of all the colors in the visible spectrum. It is produced when light from a source, such as the sun or a light bulb, contains a mix of different wavelengths of light. When these wavelengths combine, they create the perception of white light to our eyes.
Red light has longer wavelengths than white light, which contains a mix of all visible wavelengths. Red light is at the longer end of the visible spectrum, while white light is a combination of all visible colors. Red light is often associated with warmth and relaxation, while white light is seen as neutral and bright.
No, white light is a combination of all visible colors of light. This is because white light contains all the wavelengths of light in the visible spectrum, which our eyes perceive as white when combined.
When combining all colors of light, white light is formed. White light contains all the wavelengths of the visible spectrum, which are perceived by our eyes as different colors.
White light is a combination of all the colors in the visible spectrum. It differs from other colors in the spectrum because those colors are individual wavelengths of light, while white light contains all the wavelengths mixed together.
All of the wavelengths of VISIBLE LIGHT.
Sunlight contains all the colors (wavelengths) in the visible light spectrum. This is evidenced by the colors seen in rainbows.
The color of the object that you see will depend on the wavelengths of light that are reflected. Objects appear a certain color because they absorb certain wavelengths of light and reflect others. White light contains all colors of the spectrum, so the color you see is the result of the wavelengths that are reflected by the object.
All of the electromagnetic spectrum can be reflected. White light is a combination of all colors. They all reflect, red is among them.
