ABSTRACT R.Velmurugan formula is about light and shadow, light is a electromagnetic wave hence we can generalize the R.Velmurugan formula to electromagnetic wave and it's absence .Like cargo engine I (R.Velmurugan) ideally generalize my formula to electromagnetic wave and it's absence due to an electromagnetic wave insulator hence derivation of Gauss law in electrostatics , Brewster law in optics and Poisson equation in electromagnetic potential is possible .
