When white light travels through glass, ...

When white light travels through glass, the refractive index of glass (`mu`=velocity of light in air/velocity of light in glass) is found to vary with wavelength as `mu=A+(B)/(lambda^(2))`. Using the principle of homogeneity of dimensions, Find the SI units in which the constants A and B expressed.
