This is the original electro magnetic spectrum song by Emerson & Wong Yann from Singapore. There is a lot to say about it. Maybe you want to mention the quality of the music, song or singing. This has already been done by over 1,5 million viewers!
The strength of the song / video lies in the large amount of supporting images and recognizable examples. Tiny drawback is that the image of the spectrum starts with gamma rays on the left where the song starts with radio waves and ends with gamma rays. This may be a bit confusing when you are used to reading from left to right.
