Given information

Given energy levels,

 

 

Step-by-step explanation

Step 1.

firstly, one has to calculate the energy of the electron is given energy levels, i.e., .

and then calculate the energy difference, 

and, For hydrogen atom, the energy of an electron in an orbital with quantum number   is;

 

    

Further putting the values one get, 

 

But the energy of the photon must always be positive. So,
