Refractive Index n is inversely proportional to wavelength of light.
But refractive index = Speed of light in Vaccum/Speed of light in medium
Hence, speed of light in media is directly proportional to wavelength...
Since wavelength increases from Violet to Red,
Red travels the fastest...
Violet travels the slowest...
