Red light has the longest wavelength.
Red color in the visible spectrum has longest wavelength.
The longest visible wavelength is that of the last coloryou can see on the red end of the spectrum.
Red.
Violet light has the lowest wavelength in the visible light spectrum.
The colour of visible light with the longest wavelength is red (approximately 700 nanometres).
Red has the longest wavelength among the visible colors.
The color RED has the longest wavelenth, and the color VIOLET has the shortest wavelenth. ---- Also Wavelenth is inversely propotional to frequency, so we can also say that color VIOLET has longest frequency and color RED has the shortest. VIBGYOR V-Violet (Highest Frequency, Shortest Wavelenth) I-Indigo B-Blue G-Green Y-Yellow O-Orange R-Red (Highest Wavelenth,Shortest Frequency)
Your question is meaningless. Light is electromagnetic radiation and the colour of light depends on the wavelength of this radiation. There is no such thing as a "weak" wavelength.
The fastest color in the rainbow is blue, as it has the shortest wavelength among the visible colors of the spectrum.
Red light has the longest wavelength among the visible light spectrum because it carries the least amount of energy. This longer wavelength makes red light less energetic than other colors like blue or purple, which have shorter wavelengths.
The ultraviolet spectrum is 'beyond' (ultra) the violet part of the visible spectrum, that is, beyond the short end of the wavelength range. The infrared spectrum is 'within' (infra) the long end of the wavelength range. The two terms have nothing to do with color, which defines the visible spectrum between violet and red.
The seven color categories of visible light, in order of increasing wavelength, are violet, indigo, blue, green, yellow, orange, and red. These colors can be remembered using the acronym ROYGBIV. Together, they form the visible spectrum, which is part of the electromagnetic spectrum and can be observed in phenomena like rainbows. Each color corresponds to a specific wavelength range, with violet having the shortest and red having the longest.
