How do you make violet light?

mix roughly 2 parts blue to 1 part red to make violet; mix equal part yellow and blue to make green. You may also want to try this with a Gamblin Cadmium Yellow Light.

What is the frequency of light having wavelength?

The wavelength of visible light implies it has a frequency of roughly 430 to 750 terahertz (THz). The speed of light in a vacuum is experimentally found to be 299,792,458 meters per second, which is approximately 3 × 10⁸ meters per second.
