Visible wavelengths pass largely unattenuated through the Earth's atmosphere via the "optical window" region of the electromagnetic spectrum. An example of this phenomenon is when clean air scatters blue light more than red light, and so the midday sky appears blue. The optical window is also referred to as the "visible window" because it ...


Main Difference. Red and blue light differ from each other largely. Basically, usually, phrases the higher the vitality of the sunshine, the higher can be the frequency of the sunshine and this goes vice versa with the wavelength that is the elevated the vitality of the sunshine, the shorter can be the wavelength of the sunshine.


Download a diagram and explanation of the chromatic dispersion of a ray of light containing wavelengths corresponding with red, green and blue.


The RGB color space for instance is a color space corresponding to human trichromacy and to the three cone cell types that respond to three bands of light: long wavelengths, peaking near 564–580 nm (red); medium-wavelength, peaking near 534–545 nm (green); and short-wavelength light, near 420–440 nm (blue).


Key Difference – Red vs Blue Light The key difference between Red and Blue light is the impression created at the human retina. It is the perceptive understanding of the difference between two wavelengths.


Some people over at Laser Pointer Forums have a variety of blue lasers at wavelengths of 445, 450, 460, and 473 nm. They upload photos, then discuss whether the photo seemed to accurately capture the color. The consensus is that 445 and 450 nm look blue with a tinge of violet, 460 nm looks like pure blue, and 473 nm is more like sky blue.


The colours we see are the wavelengths that are reflected or transmitted. For example, a red shirt looks red because the dye molecules in the fabric have absorbed the wavelengths of light from the violet/blue end of the spectrum. Red light is the only light that is reflected from the shirt.


The image below shows light's visible spectrum, which runs from violet to red. You might recognize the spectrum as the order of colors in a rainbow. But light waves can also have wavelengths lower or higher than the wavelengths in the visible spectrum, and many familiar types of radiation are just light waves with other wavelengths.


The progression of colors from red through violet is identical to that on the linear scale. The circular wavelength scale outside the color wheel shows the wavelength connection between the linear and circular sequences. The purple region in the color wheel is a notable difference between the two sequences.


Blue light has a wavelength of 450-495 nm (nanometers or billionths of a meter). It falls in the higher frequency of the visible light spectrum. Red has the longest wavelength (620-750 nm) and ...
