WebThe refractive index of any substance is best described as a complex number, such as 1.34 + i 0.00067. The real part of this number is the "ordinary" refractive index as discussed above, whilst the imaginary part indicates the amount of absorption. If the imaginary part is zero, the substance is non-absorbing.
