The k-shell ionization energy of iron is 8500 ev, and it's l-shell ionization energy is 2125 ev. what is the wavelength of kalpha x-rays emmited by iron?

Explanation:

First of all, we need to calculate the energy of the x-ray photon emitted during the transition from K-shell to L-shell, and this energy is equal to the difference in energy between the two levels:

Converting into Joules,

Now we know that the energy of the photon is related to its wavelength by:

where

h is the Planck constant

c is the speed of light

is the wavelength

Re-arranging the equation for , we find

overcharge is the right answer system

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
