How refraction index depend on wavelength?
Can you explain why this happens?
Sure. One way to explain this is through the concept of dispersion, which is the process by which light separates into its various colors. This phenomenon happens because different colors of light experience different amounts of refraction as they pass through a medium. This is why a prism can create a rainbow effect. So, essentially, the change in refraction index with wavelength is a result of the different colors of light interacting with the medium differently.
