An electron is trapped in an infinite square-well potential of width 0.2 nm. If the electron is initially in the n = 4 state, what are the various photon energies that can be emitted as the electron jumps to the ground state? (List in descending order of energy. Enter 0 in any remaining unused boxes.)

Please read the answer below

Explanation:

The energies in a infinite square-well potential of width a is given by

where me=9.1*10^{-31}kg, hbar=1.05*10^{-34}Js and a= 0.2*10^{-9}m.

From the state n=4 the electron can pass to state n=3, n=2 and n=1. The different transitions can be

n4->n3=E4-E3

n3->n2=E3-E2

n2->n1=E2-E1

Hence, by replacing we have that the photon energies emitted are given by

However, the transitions T4-2, T4-3, T3-1 are also allowed

hope this helps!!

i don't understand is there any other way you can rephrase it plz let me know in the comments and i will do it.

explanation:

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
