  • Option 1)

    λ1 ≤ λ2

     

  • Option 2)

    λ1 = λ2

     

  • Option 3)

? decay -

\gamma ray emitted when nucleus undergoes radio active decay left it in excited state 

- wherein

After emission of \alpha ,\beta  particle the product nucleus formed in excited state

 

 Energy of gamma ray is greater Than that of X rays since \gamma \rightarrow nuclear decay X ray\rightarrow Atom ic Transition

\therefore \lambda _{1}>\lambda _{2}

λ1 ≤ λ2

 

Option is incorrect

Option 2)

λ1 = λ2

 

Option is incorrect

Option 3)

λ1 > λ2

 

Option is correct

Option 4)

λ1 < λ2

Option is incorrect
