In the SPF calculation formula, how do we calculate the constant values of spectral intensity for the rest of the wavelengths?

29 March 2022 0 3K Report

In the SPF calculation formula, fixed values of spectral intensities are specified for only seven wavelengths. On the other hand, because the formula is continuous, it is not possible to put only seven wavelengths and calculate them discrete. How to calculate the constant value of spectra for the rest of the wavelengths?
