Variable sunlight velocity

In this paper variable sunlight velocity was examined. The sunlight is electromagnetic waves. The velocity of light Einstein states that to constant, however, light velocity is changeable. This is influenced to the 5G and 6G generation wireless networks. The 6G technology will improves areas of imaging presence technology. Working in conjunction with artificial intelligence, the computational infrastructure will be able to autonomously determine the best location. The radiance at the center of the Sun's disk is somewhat higher than the average over the whole disk due to limb darkening. The equation of electromagnetic field was extended in this paper.
