A physically real wave associated to any moving particle and propagating in a surrounding material medium was introduced by Louis de Broglie. He proposed the physical concepts of wave - particle duality of matter & the presence of matter waves & these concepts gave rise to an entirely ‘new physics’ known today as ‘quantum mechanics’. In 1927 , the experimental proof of matter waves was given by Davisson & Germer . Both relativity and quantum theory, the two pillars of fundamental physics, are co-related in this paper to make them also explain the physical phenomena they describe. A few years after de Broglie's insight into the wave nature of matter, Schroedinger was able to make his famous equation for the development of matter waves . Einstein had realised that matter was spherical and spatially extended and thus the electron was not a point particle, but rather, a structure of space. Doppler effect in matter waves on the basis of wave structure of matter (WSM) has been studied previously & in the present work an attempt has been made to connect the quantum theory with the relativity. The SRT time dilation , length contraction , relativity of mass and energy equivalence formulas are derived from wave structure of matter concepts. Before the WSM, there had been no known physical reason for the theoretical mass increase of relativity. Dirac's work was a clue that they are connected because spin, relativity, and QM were joined in Dirac's work, albeit theoretically. The WSM now reveals their simple physical connection - Doppler effects.
