A white light, as we all know, is composed of seven lights VIBGYOR. Each of the component lights has distinct frequency ranging from one value to another. So, when the photons have wavelength of 600 nm it becomes a yellow light and when it changes to 700 nm it becomes a red light. So, does this imply that the frequency with which a group of photons vibrate determine the colour of light? Well, in that case, with what frequencies are photons vibrating for a white light?

Best Answer
To get a perception of a white light, one has to observe simultaneously many photons having different frequencies and obeying a certain distribution function.
Keep in mind that a color is not a physical property, since it is resulted from human brain's interpretations of signals coming from eyes receptors.
