Which color would be located at the position noted in the diagram and which statement best explains why the light is separating?  Hint: Look at the announcements for today

• Red, because it has the longest wavelength, it refracts the most

• Violet, because it has the longest wavelength, it refracts the most

• Red, because it travels the slowest

• Violet because it travels the fastest
