The paper is made of cellulose, a polar substance, and the compounds within the mixture travel farther if they are non-polar. More polar substances bond with the cellulose paper more quickly, and therefore do not travel as far.

When light of different colors enters a glass prism, it bends or refracts at different angles due to their varying wavelengths. This causes the colors to separate and travel at different speeds, creating a spectrum of colors.
dispersion. This occurs because different colors of light travel at slightly different speeds through the prism, causing them to refract or bend by different amounts, separating the colors.
Different colors are the result of different wavelengths of light being reflected. When light strikes an object, certain wavelengths are absorbed while others are reflected, giving the object its color. The human eye perceives these reflected wavelengths as different colors.
Light splits up in a prism because different colors of light travel at slightly different speeds through the prism due to their different wavelengths. This causes the different colors to refract, or bend, at different angles, resulting in the separation of white light into a spectrum of colors.
A prism separates white light into colors because different colors of light travel at different speeds when passing through the prism. This causes the light to bend at different angles, resulting in the dispersion of light into the various colors of the rainbow based on their wavelengths.
Different Colors Of Light Travel At Different Speeds.
When light of different colors enters a glass prism, it bends or refracts at different angles due to their varying wavelengths. This causes the colors to separate and travel at different speeds, creating a spectrum of colors.
Because light travels at different velocities, and various colors of light also travel at different speeds in optical media.

Light splits up in a prism because different colors of light travel at slightly different speeds through the prism due to their different wavelengths. This causes the different colors to refract, or bend, at different angles, resulting in the separation of white light into a spectrum of colors.
it refracts because it travels in different velocities and other colors of light travel in different speeds When light crosses a boundary between mediums, it changes speeds, and it bends or changes the angle that it is travailing at when it crosses the boundary.
A prism separates white light into colors because different colors of light travel at different speeds when passing through the prism. This causes the light to bend at different angles, resulting in the dispersion of light into the various colors of the rainbow based on their wavelengths.
The phenomenon is called dispersion, which occurs because different colors of light travel at different speeds as they pass through a prism, causing them to spread out and form a spectrum.
no
yes they do
