What is white light?
White light is the light coming from the Sunlight in the form of electromagnetic wave.
Newton used the prism and white light to observe the effect of the spectrum formed. He also used red light to see the different effects by the prism. This experiment was just a study based on his observations. It has nothing to do with controlling the event.
