A science experiment in class demonstrated that when white light passes through a prism, it is dispersed into a rainbow of colors, which we know as the visible spectrum. Each color represents a different light wavelength. Now, consider a blue substance. This substance appears blue because it absorbs light of certain wavelengths and reflects or transmits blue light to our eyes. Based on this information, which principle or theory explains why substances have different colors?

The color of a substance is determined by which wavelengths of light are absorbed by the substance and which are reflected. This is the basis of the Theory of Color.

The color of a substance is determined by the speed at which light travels through it, known as the Theory of Light Speed.

The color of a substance is determined by the temperature of the light it absorbs and reflects, known as the Theory of Thermal Color.

The color of a substance is determined by the angle at which light hits it, forming the basis of the Theory of Light Angle.

The color of a substance is determined by the intensity of light it reflects, which is the basis of the Theory of Intensity.
