please tell me the main concepts or points that are must for wave mechanics

Dear student,

We know since Louis de Broglie that matter particles exhibit wave properties. Indisputably, matter works by means or waves. Let us make it perfectly clear : there is no alternative. At this stage, it is not an assumption, it is a certainty.

Additionally, the electron is not a metal marble covered in chrome. It cannot be made of matter. It is rather matter which is made of electrons. So, let us postulate that the electron is a standing wave system. Furthermore, these waves cannot be plane. They should be spherical.
