I could say that shorter wavelengths move faster, but that would be wrong.
The truth is that all wavelengths/colors travel at the same speed.
All colors of light travel at the same speed in a vacuum, which is the speed of light. However, in mediums like air or water, the speed of light differs for different colors due to their different wavelengths and refractive indexes. Blue light generally travels slower than red light in these mediums.
Different colors refract at different angles because they have different wavelengths. When light enters a different medium, such as air to water, the speed of light changes, causing different colors to bend at different angles due to their unique wavelengths being affected differently. This results in the separation of colors, known as dispersion.
Colors appear to bend when they pass through materials of different densities, such as air and water, due to refraction. Refraction occurs because light waves change speed when moving from one medium to another, causing them to bend. This bending of different colors of light at different angles creates the phenomenon of spectral dispersion.
Nothing special. But when light travels from one medium to another (from air to water for example) it is refracted. One answerer said a rainbow. A rainbow is caused by the different wavelengths (colors) of light are refracted at slightly different angles, so that we see different colors appearing at different positions.
Yes, the refractive index of a material can vary with the color of light because different colors of light have different wavelengths, which interact with the material's atoms in different ways. This can lead to variations in the speed at which light travels through the material, resulting in a different refractive index for different colors.

The speed of light is different in different substances ... air, water, glass, jello, etc.
Because all the constituent colors of white light have same speed so, refractive index for the constituent colors are same for air as a result dispersion doesn't occur.
You can that they're all identical.

Yes, the speed of violet light in glass is higher than the speed of red light. This is due to the phenomenon of dispersion, where different colors of light are refracted at different angles as they pass through a medium, causing them to travel at different speeds.

Refraction. White light is a mix of colors in the first place; these colors have different indices of refraction. That is, when moving from air to glass, as in a prism, they will bend at slightly different angles.
When light travels through a prism, it is bent or refracted as it passes from air into the prism and then again as it exits the prism. Different colors of light are refracted by different amounts due to their different wavelengths, causing them to separate. This separation creates a rainbow effect known as dispersion.
All wavelengths are the same physical phenomenon ... electromagnetic radiation ... whose speed depends on the electrical properties of the medium in which it is propagating. Why would you think that they should travel at different speeds ?
