What is the shortest-wavelength x-ray radiation in m that can be generated in an x-ray tube with an applied voltage of 93.3 kv? m (b) calculate the photon energy in ev ev (c) explain the relationship of the photon energy to the applied voltage. the maximum photon energy is just the applied voltage times the electron charge. the value of the voltage in volts equals the value of the maximum photon energy in electron volts. the maximum photon energy is just the applied voltage times the electron charge. the value of the voltage in volts equals the inverse of the value of the maximum photon energy in electron volts. the maximum photon energy is just the applied voltage divided by the electron charge. the value of the voltage in volts equals the value of the maximum photon energy in electron volts. the maximum photon energy is just the applied voltage divided by the electron charge. the value of the voltage in volts equals the inverse of the value of the maximum photon energy in electron volts.

(a)

The x-rays in the tube are emitted as a result of the collisions of electrons (accelerated through the potential difference applied) on the metal target. Therefore, all the energy of the accelerated electron is converted into energy of the emitted photon:

where the term on the left is the electric potential energy given by the electron, and the term on the right is the energy of the emitted photon, and where:

is the electron's charge

is the potential difference

is the Planck constant

is the speed of light

is the wavelength of the emitted photon

Solving the formula for , we find:

(b) 93300 eV (93.3 keV)

The energy of the emitted photon is given by:

where

h is Planck constant

c is the speed of light

is the wavelength of the photon, calculated previously

Substituting,

Now if we want to convert into electronvolts, we have to divide by the charge of the electron:

(c) The following statements are correct:

The maximum photon energy is just the applied voltage times the electron charge. (1)

The value of the voltage in volts equals the value of the maximum photon energy in electron volts.

In fact, we see that statement (1) corresponds to the equation that we wrote in part (a):

While statement (2) is also true, since in part (b) we found that the photon energy is 93.3 keV, while the voltage was 93.3 kV.

b) phosphorus pentoxide

there are no correct statementd on the list of choices you provided.
