what is the wavelength of white light？
400 – 700 mmHence, white cannot be assigned to a single wavelength as it is composed of wavelengths of different colors. The white light has a wavelength between the ranges of 400 – 700 mm.
Accordingly,Is white light all wavelength?
White light is actually made of all of the colours of the rainbow because it contains all wavelengths, and it is described as polychromatic light.
One may also ask,What is the frequency and wavelength of white light?
The light emitted has a peak wavelength of about 550 nm, which we perceive as visible white light (or slightly yellowish).
Likewise,What is green light wavelength?
The visible green light has a wavelength of about 510 nm.
Then,What is wavelength of blue light?
between about 450 and 495 nanometersBlue light has shorter waves, with wavelengths between about 450 and 495 nanometers. Red light has longer waves, with wavelengths around 620 to 750 nm. Blue light has a higher frequency and carries more energy than red light.
More simply, this range of wavelengths is called visible light. Typically, the human eye can detect wavelengths from 380 to 700 nanometers.
The fact that you see all the fundamental colors present in a rainbow (which is sunlight split by mist) and no colors are missing is direct evidence that sunlight is white. The sun emits all colors of visible light, and in fact emits all frequencies of electromagnetic waves except gamma rays.
White light is a combination of lights of different wavelengths in the visible spectrum. Passing white light through a prism splits it up into the several colours of light observed in the visible spectrum between 400 nm and 780 nm.
White light is a combination of all colors in the color spectrum. It has all the colors of the rainbow. Combining primary colors of light like red, blue, and green creates secondary colors: yellow, cyan, and magenta.
Some consider white to be a color, because white light comprises all hues on the visible light spectrum. And many do consider black to be a color, because you combine other pigments to create it on paper. But in a technical sense, black and white are not colors, they're shades. They augment colors.
A true white light will have equal intensity in the low-end and the high-end of the spectrum, therefore more intensity on the high-end part than a yellowish light, and will be more energetic.
For example, an orange color is associated with a wavelength of 600 nm. However, the same color can be produced with a combination of two light beams, one being red with a wavelength of 700 nm, and another being yellow with a wavelength of 580 nm, with no orange component.
Higher frequency (with shorter wavelength) has more energy: Red light has lower frequency, longer wavelength and less energy. Blue light has higher frequency, shorter wavelength and more energy.
