can you explain QAUNTUM number theory and debrolies wave length and bohrns atomic model

@ komali 
ask one ques in one tag , 
debroglie put forward the concept of dual nature of particle , that is the wave and the particle nature , and he proposed the formula for the wavelength of the particle as well as for the microscopic poarticle . 
acc to the formula 
lambda = h/p 
where lambda is the wavelength , and h is the plancks constant , and p is the momentum. 
u can write momentum = m * v ( mass * velocity ) 
as nature prefers symmetry , so , due to that he gave the dual nature of particle . 
HOPE IT CLEARS 
ALL THE BEST ..

QUANTUM NUMBERS: The set of numbes which are used to describe the complete description of an electron(size,energy,shape of orbital & spin of electron) is knowns as quuantum numbers.
