passing through a prism or diffraction grating, which causes the different wavelengths of light to separate and be seen as distinct colors. This phenomenon is known as dispersion.
Studies of earthquake waves passing through Earth support the conclusion that the Earth has distinct layers with varying densities and composition. This is because seismic waves travel at different speeds and paths as they move through different layers, providing information about the internal structure of the Earth.
