The method of images in electrodynamics involves a clever mathematical technique to simplify complex boundary value problems. This method leverages the principle of mirror charges to create a virtual image system that mimics the behavior of the actual charge distribution. By strategically placing these imaginary charges, one can construct a scenario with known boundary conditions, facilitating the solution of electrostatic and magnetostatic problems. DJ Griffiths' elucidation of the method of images provides.

قادر جدا تخلي أي حد يحب الفيزياء حتى لو كانت عقدة حياتو ، أسلوبك ف الكلام وشخصيتك وكونك شخص نبغة وعبقري بهذا الشكل بيجذبوا أي حد ليك ، حقيقي من الناس المميزة ال يستحقوا وبجدارة يتقال عليهم دكاترة جامعيين " الله يزيدك من علمه

Bundle of thnks dear sir😊
Teaching method is tariffic😊😊

a point charge q is placed at a distance d from the centre of infinite conducting plane using method of image, calculate the electric potential and then electric field (e)

Question: x^2 + y^2 + z^2 is much much greater than d or d^2?
