What do the hues according to Newton represent?

1. Emotional states

2. Musical notes

3. Wavelengths

4. Life elements

The correct answer is: Wavelengths

The hues according to Newton represent wavelengths in the context of his work with light and color. Newton conducted experiments with prisms and demonstrated that white light can be refracted into a spectrum of colors, ranging from red to violet. Each of these colors corresponds to light of different wavelengths, which can be measured in nanometers. This scientific approach laid the foundation for understanding color theory, emphasizing how colors relate to the physical properties of light. While emotional states, musical notes, and life elements can be associated with colors in various fields such as psychology, music theory, and symbolism, these interpretations do not reflect Newton's objective and systematic inquiry into the physical characteristics of light. His exploration centered on the nature of light and its spectral composition, reinforcing the connection between specific colors and their respective wavelengths.
