"The refractive index of red light in glass is 1.513. The refractive index of violet light is 1.532. This slight difference is enough for the shorter wavelengths of light to be refracted more."

Two down and 5 to go ...

Difference in refraction is 0.019 - difference in wavelength is 250nm

1 nm = 0.019 /250 = 0.000076

Therefore ...

Red = about 650 nm = 1.513
Yellow = about 570 nm = 1.51908
Green = about 510 nm = 1.52364
Blue = about 475 nm = 1.5263
Purple (violet) = about 400 nm = 1.532

onward ...
