For example: I used bands 3 and 4 (Red & Near Infra Red) from Landsat 4-5 and bands 4 and 5 (Red and Near Infra Red) from Landsat 8 for NDVI calculation, but the wavelength range of band 3 in Landsat 4-5 is not exactly the same as of band 4 in Landsat 8.

Is there any way to convert things so that they are same and comparable. I got big variances between NDVI values from the two satellites and have the idea that's because the wavelengths differ.
