The order of colors from longest to shortest wavelength is red, orange, yellow, green, blue, indigo, violet (ROYGBIV).
The colors of visible light
You could memorize the seven spectrum colors in order with a word called [roygbiv] or Roy G. Biv, as most learn it. The colors of the rainbow are in the order from longest wavelength to shortest, with red having the longest wavelength and violet having the shortest. r= red o=orange y=yellow g=green b=blue i=indigo v=violet A.K.A: ROY G BIV THE COLORS OF THE RAINBOW
The sequence of the listing in the question is correct. From longest to shortest wavelength, these four categories of EM radiation do in fact list in the order: 1). infrared 2). visible 3). ultraviolet 4). X-rays
The color of visible light with the longest wavelength is red; the color with the shortest is violet. So "ROY G. BIV" lists the colors from long to short wavelength. Just to confuse you, we'll also mention that it lists them from lowest to highest frequency.
To arrange time divisions from longest to shortest, the correct order is: year, month, week, day, hour, minute, second. A year encompasses the longest duration, followed by a month, then a week, and so on, with a second being the shortest measurement in this sequence.
The colours of visible light (to humans) are the colours of the rainbow. Red has the longest wavelength and violet the shortest. There is some argument as to whether indigo should be included but if it isn't, the colours in increasing wavelength are violet, blue, green, yellow, orange and red.
The correct order of the electromagnetic spectrum from shortest wavelength to longest is gamma rays, X-rays, ultraviolet light, visible light, infrared radiation, microwaves, and radio waves.
The colors of visible light
The order of the energy spectrum from shortest to longest wavelength is gamma rays, X-rays, ultraviolet light, visible light, infrared light, microwaves, and radio waves.
In order from Longest Wavelength to shortest: Red Orange Yellow Green Blue Indigo Violet
X-rays have the shortest wavelength of those listed.
Between Yellow, Green and Violet, the Yellow color has the longest light wave. The order of the 7 rainow colors, sorted by their light waves from the longest to the shortest, is as follows: Red, Orange, Yellow, Green, Blue, Indigo and Violet.

Radio waves, microwaves, infrared, visible light, ultraviolet light, X-rays, gamma rays.
The correct order from shortest to longest wavelength for the different categories of electromagnetic radiation is gamma rays, X-rays, ultraviolet light, visible light, infrared radiation, microwaves, and radio waves.
The order of units of geologic time from longest to shortest is: eon, era, period, epoch.
