What is the general term for the phenomena associated with wave patterns in light?

The correct answer signifies the broad concept encompassing various wave phenomena involving light. The term "spectrum" refers to the range of electromagnetic radiation, including visible light, which illustrates how different wavelengths are perceived as different colors. This term encapsulates the overarching behavior of light waves and their interaction, as well as associated phenomena like interference and diffraction, which are specific instances of light behavior.

In relation to wave patterns, the spectrum demonstrates how light can be decomposed into different wavelengths, leading to the creation of colorful patterns, such as rainbows or various colors of light emitted from a prism. Each wavelength correlates to specific patterns and behaviors of light, showcasing its wave-like properties. Understanding the spectrum is crucial for a comprehensive grasp of how light behaves in various contexts.
