No, not at all.
no
You can that they're all identical.
The visible light part of the electromagnetic spectrum is below the ultraviolet but above infrared. Purple light has the highest wave length and red has the lowest.
No some of them are different colours
They are not all the same length. If that was the case all circles would be the same size.
Reflects all light beams which have the wave length of the color of that object. Each color has a particular wave length in the electromagnetic spectrum.
Very roughly from 380 nanometers (red) to 750 nanometers (blue/violet). The 'limits' aren't the same for all eyes.
They were not all the same length.
White light is what we see when light of all (or most) of the frequencies in the visible spectrum are emitted together from the same source. It is the combination of every visible light wave.
In general no. A regular hexagon has the same length on all sides. Also, there are other hexagons with the same length on all sides that are not regular.
No.
No, they come in different colours.
