b) Calculate the matrix which represents the Hamiltonian(adsbygoogle = window.adsbygoogle || []).push({});

H= 1{(L)^2}/2I + Alpha*(L^z)

H = part A + part B

where alpha is a constant and so is I and also L^2 = Lx^2 + Ly^2 + Lz^2 (1)

heres what i have done. i have calculated L^2 From adding matrices from 1 and it came to 2(h^2)*the identity matrix and then i have added together Part A and part B to get matrix..

question is the constant I in the question the identity matrix so i can cancel both I's as i have found that L^2 =2I. And then how do i add (h^2) to a matrix,i am confused i am missing something
