Here is Your Answer...!!!!

⭐Actually welcome to the concept of the MODERN PHYSICS / ATOMIC STRUCTURE. .⭐〽

⭐Basically this is the concept of the

⭐EINSTEIN'S EQUATION OF ENERGY AND THE PLANKS QUANTUM THEORY

⭐we know that energy is given by

⭐E = mc^2 according to the theory of relativity

⭐Also by the Quantum theory we know that

⭐E = hv ,since here V = frequency and we know that ( v = c/lambda )

⭐so now equating both we get as

⭐hc/ lambda = mc^2

⭐now cancelling velocity from both side and rearranging in terms of wave length (lambda ) we get as

⭐-\ ( lambda) = h ÷ mc

⭐since we know that momentum (p) = mv

⭐so replacing we get as the DE - broglies wavelength.

⭐lambda = h/ p
