Complete Question

(A) Find the excitation energy from the ground level to the third excited level for an electron confined to a box that has a width of 0.125 nm .

(B) The electron makes a transition from the n=1 to n= 4 level by absorbing a photon. Calculate the wavelength of this photon.

A

B

Explanation:

Considering question a

From the question we are told that

 The width of the box is  

Generally the energy level of a particle confined to a box is mathematically represented as

Generally the excitation energy is mathematically represented as

From the question    

   Here h  is the Planck's constant with a value  of  

         m is the mass of  electron with value  

So

=>    

=>    

=>    

Considering question b

Generally the energy level of a particle confined to a box is mathematically represented as

Generally the excitation energy is mathematically represented as

From the question  

 Here h  is the Planck's constant with a value  of  

         m is the mass of  electron with value  

So

=>      

=>        

=>        

Gnerally the wavelength is mathematically represented as

=>      

=>      

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
