  • question_answer
    In \[{{\Psi }_{321}}\] the sum of angular momentum, spherical nodes and angular node is -

    A) \[\frac{\sqrt{6}h+4\pi }{2\pi }\]  

    B)        \[\frac{\sqrt{6}h}{2\pi }+3\]

    C) \[\frac{\sqrt{6}h+2\pi }{2\pi }\]  

    D)        \[\frac{\sqrt{6}h+8\pi }{2\pi }\]

    Correct Answer: A

    Solution :

    [a] \[{{\Psi }_{321}}:n=3,\ell =2,m=1\] Angular momentum \[=\frac{h}{2\pi }\sqrt{\ell (\ell +1)}=\frac{\sqrt{6h}}{2\pi }\] Spherical nodes \[=3-2-1=0;\] Angular node = 2 Sum of all the above \[=\frac{\sqrt{6}h}{2\pi }+2=\frac{\sqrt{6}h+4\pi }{2\pi }\]
