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.

en.wikipedia.org/wiki/Visible_spectrum

The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light.A typical human eye will respond to wavelengths from about 380 to 740 nanometers. In terms of frequency, this corresponds to a band in the vicinity of 430–770 THz.

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.

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.

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 ...

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).

Red light has a slightly longer wavelength than blue light. Red light (at one end of the visible spectrum) has a longer wavelength than blue light. However, another way of distinguishing between the different colors of light is by their frequency , that is, the number of waves that pass by a point every second.

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.

In the visible light spectrum, the wavelength of red light ranges from 622 to 780 nanometers. Red light has the longest wavelength and the shortest frequency. Violet light, which has the shortest wavelength, is at the other end of the visible spectrum.

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.
