White light is a combination of all visible wavelengths of light. It contains a broad spectrum of colors ranging from violet to red. The perception of white light occurs when all these colors are present in roughly equal amounts and properly balanced.
While red is indeed one of the wavelengths present in white light, it is not accurate to say that red is the "strongest" or "first" wavelength emitted from white light. In fact, white light consists of a continuous spectrum of wavelengths, with no single wavelength dominating over others.
The perception of white light is a result of our eyes' response to the combined stimulation of all three types of color receptors: red, green, and blue cones in our retinas. These cones are sensitive to different parts of the visible spectrum, and when they are all stimulated in the right proportions, we perceive white light.
So, while red is one of the constituent colors of white light, it is incorrect to say that it is the closest or most similar to white light. White light contains all visible wavelengths and is perceived as a balanced mixture of colors.
