Dispersion
Dispersion is the process of separating white light into its constituent colors. This is usually done using a prism, which refracts (bends) different colors of light by different amounts, causing them to spread out and become visible as a spectrum. Dispersion is a fundamental property of light and is responsible for phenomena such as rainbows and the colors seen in gemstones.
Study Guide
- Definition: Dispersion is the process of separating white light into its constituent colors.
- Prism: A prism is commonly used to demonstrate dispersion. When white light enters a prism, it is refracted (bent) at different angles depending on the wavelength of the light, resulting in the separation of colors.
- Spectrum: The spread of colors resulting from dispersion is called a spectrum. The colors of the spectrum include red, orange, yellow, green, blue, indigo, and violet (often remembered by the acronym ROYGBIV).
- Applications: Dispersion is responsible for phenomena such as rainbows, the colors seen in gemstones, and the operation of optical devices such as spectrometers.
- Understanding: Understanding the process of dispersion helps in comprehending the behavior of light and the formation of colors in various natural and artificial contexts.

LIFE SCIENCE
From Molecules to Organisms: Structures and Processes
Create representations to explain the unique and diverse life cycles of organisms other than humans (e.g., flowering plants, frogs, butterflies), including commonalities such as birth, growth, reproduction, and death.
Unity and Diversity
Construct an argument from evidence to explain the likelihood of an organism’s ability to survive when compared to the resources in a certain habitat (e.g., freshwater organisms survive well, less well, or not at all in saltwater; desert organisms survive well, less well, or not at all in woodlands).
Create models that illustrate how organisms and their habitats make up a system in which the parts depend on each other.
