1. What is the key scientific principle?Represents a continuum of wavelengths, particularly in the electromagnetic spectrum
2. What is the primary use?To organize and understand phenomena that exhibit a range of overlapping properties
3. What is a spectrum in science?A spectrum is a smooth line of colors that shows how light is made of many different colors, each with its own wavelength.
4. Why did Isaac Newton discover the spectrum?He used a prism to split sunlight and saw that white light is actually many colors together, proving light has a range of wavelengths.

Continuum: A continuous sequence in which adjacent elements are indistinguishably related, lacking discrete breaks.
Electromagnetic Spectrum: The entire range of electromagnetic radiation, ordered by frequency and wavelength.
Spectroscopy: The scientific study of the interaction between matter and electromagnetic radiation as a function of wavelength or frequency.
