Pete - knocking the poop off Marinka was a pleasure... what 'til you see what job I have lined up for you on Solitude on our next sail, you any good at unblocking heads? Ha ha.
Everyone knows that red is the fastest colour:
Light travels at a constant speed in vaccum... 3 x 10^8 m/s...
But in media like air, glass, different wavelengths in the electromagnetic spectrum travel at different speeds.
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..
