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 shortest on this list is gamma rays.The list is stated almost but not quite in the correct order, from longest to shortest wavelength. It should read:RadioInfra-redUltravioletX-raysGamma rays
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
well think about it the planets closer to the sun have the fastest orbit so knowing that the planets are already in order from shortest to longest orbit.
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.
As far as visible light is concerned violet has highest frequency and shortest wavelength where as red has lowest frequency and so longest wavelength VIBGYOR is the order of colours in the visible spectrum
The colors of visible light
radiowaves, microwaves, infra-red, visible, ultraviolet, x-rays, gamma rays
In order from Longest Wavelength to shortest: Red Orange Yellow Green Blue Indigo Violet
X-rays have the shortest wavelength of those listed.

The human eye is sensitive to electro-magnetic waves, within a very narrow band. This is known as 'White light'. This very narrow range has differing wavelengths. Red being the longest wavelength and blue being the shortest wavelength. which we see in a yellow is between this long/short limits of wavelength , hence we see yellow. Sir Isaac Newton( he of gravity fame), in his treatise named 'Optics'. demonstrated the splitting of white light into the colours of the rainbow. Going from longest wavelength to shortest wavelength , the colours are red, orange, yellow, green, blue, violet, & indigo. Which we see in a natural rainbow in that order. The human eye is NOT sensitive to ultra-violet(UV) nor to infra-red, as they are just outside the sensitivity of the human eye.

This is in order from longest to shortest, but you get the point.Interphase about (78.92%) - prophase (14%) - metaphase (4%) - telophase (3%) - anaphase (0.08%)
The centre spot will be dark even when we use white source. As the radius of the ring is directly proportional to the square root of the wavelength, the violet being the shortest wavelength will come first and red will be the last as its wavelength is the longest in the visible region. Any how we cannot get sharp coloured rings around the black spot. Instead overlapping occurs and just multicoloured rings can be seen.
