Question
frequency are direllly energy and If the frequency of an x-ray is doubled, the ener is doubled. This relationship was first described b the German physicist Max Planck (858-1947). TI 1 Second relationship between photon energy and frequency mathematically described in the formula: where: E photon energy (eV) TI-30Xa h Planck's constant 4.15 x 10 15 eV-sec A photon frequency (Hz) From this formula, it is possible to calcula the frequency of an x-ray when given the x-ra photon's energy.

E = energy of photon = 72 KeV = 72 (1000) (1.6 x 10-19) J = 1.15 x 10-14 J
f = frequency
using the equation
E = hf
1.15 x 10-14 = (6.63 x10-34) f
f = 1.73 x 1019 hz
