Colors are a name:
ROY G. BV
How Roy G. Bv Lost a Vowel
The sequence of colors red, orange, yellow, green, blue, and violet may be remembered by memorizing the name of that fine fellow "ROY G. BV". This was originally "ROY G. BIV", because it used to be common to call the region between blue and violet "indigo". In modern usage, indigo is not usually distinguished as a separate color in the visible spectrum; thus Roy no longer has any vowels in his last name.
Here is a picture that I hope helps.

Higher the frequency ( shorter the wavelength) more energetic the radiation.Human eyes is sensitive to a very small part of the electromagnetic spectrum , naturally called the visible part.Here are some tips.
There is greenery all around. Green colour lies in the middle of the visible spectrum.If you pull a muscle , you are given infrared treatment.Infrared means below red. Red is the least energetic colour . Ultraviolet ( beyond violet) radiation can cause cancer; violet is on the high energy end.Ozone layer in the atmosphere absorbs UV radiation from the sun.
X-rays are used for photographing bones; they are powerful enouh NOT to be absorbed by bones. Gamma rays are even stronger. Note that both the names X and Gamma are simply letters of alphabets.Exploding stars emit huge amounts of X and Gamma rays , quickest way of getting rid of energy
On the lower end of energy spectrum , on the red side , you have radio waves, which are very weak, ie have v long wavelengths. They can travel far.They are used for communications.
I hope this helps

Well for visible light it'll go somewhere from 390~400 to 6 or 700nm I think. And rainbow colors. Divide it up in rainbow colors from blue to red. You can estimate wavelength this way.

Radio - Microwave - Infrared - Visible Light - Ultra Violet - X-Rays - Gamma Rays.
Red, Orange, Yellow, Green, Blue, Indego, Violet
I don't know any tricks to it, but if your good...

RMIVUXG...sturdy success looking a mnemonic for that. initiate with seen, and understand that it really is bordered by employing infrared and ultraviolet. then you actually in basic terms tack on radio and microwave on the lengthy end, and x-ray and gamma ray on the quick end.
