If you shine light through a prism you see a rainbow or more correctly the colour spectrum.
VIsual light
Most of the electromagnetic spectrum is not visible.

yes it does make purple
Violet (purple) is the highest energy color in the visible spectrum. It has a wavelength of about 400nm (4x10-8m), the lowest of all visible light.
White light, like sunlight, is made up of many different colors of light. We see this when raindrops split the light into a rainbow. The purple part of a rainbow is violet light. Some parts of the light spectrum are not visible to the human eye. The invisible part next to purple (violet) is called the ultraviolet spectrum.
Flowers in general, and San Mateo Woolly Sunflowers included, utilize light energy in the purple (reds and blues) range. Colors on the purple end of the spectrum have the highest light energy.Blue light - responsible for vegetative or leaf growth (fluorescent light)Red plus Blue light - encourages flowering (full spectrum or "grow lights)
If you separate "white" light in a prism, you get the visible spectrum, (ROYGBIV). If you get that back together, you get "white" light. If you mix red and blue, you get purple, and so on.
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.

Purple does exist and it is caused by reflection of that portion of the electromagnetic spectrum.
No, a spectrum of light with no gaps can not be achieved.
