What's the wavelenght of pure red

[BurningLaserGuy]

Lotus_Darkrose hit the nail on the head. These are not the ypes of threads people will reference for years to come either. These are the questions only asked by new folks who haven't seen the wavelengths yet(typically, some exceptions). New folks are going to start a new poll. Like Lotus said: it is clutter.

The medium for this exploration exists. Just keep to a single thread.

Exactly, I didn't see 635, 632nm or darker than 660nm in person. If I had seen
those wavelenghts, I wouldn't put this question.
