Answer 2

Hey mate here is your answer

White light is a mixture of all the colours in the visible spectrum, all the colours that the eye can see, roughly in the proportions in which they are present in sunlight.

Because the eye adapts to surrounding colours, there is no exact definition of white light. Any light source with a reasonable amount of light of all visible colours will be regarded as white. Some different variations of white are known by their colour temperature - the temperature of the surface which would emit that mixture of colours.


OR


White light is light such as sunlight that contains all the colors of the visible spectrum in roughly equal amounts.
