Calculate the minimum-wavelength x-ray that can be produced when a target is struck by an electron that has been accelerated through a potential difference of 21.0 kV and 1.09 ✕ 102 kV.

(a)    21.0 kV

λmin =  m



(b)    1.09 ✕ 102 kV

λmin =  m



(c)    What happens to the minimum wavelength as the potential difference increases?

X-rays are produced when the electron stream in an x-ray tube knocks an electron out of a low-lying shell of an atom in the target, and an electron from a higher shell falls into the lower-lying shell. The x-ray is the photon given off as the electron falls into the lower shell. The most intense x-rays produced with a copper target have wavelenghts of 1.542A and 1.392A. These x-rays are produced when an electron from the L or M shell...

Dentists use x-rays to image their patients’ teeth and bone. The x-ray tubes that generate x-rays contain an electron source separated by about 10cm from a metallic targets. The electrons are accelerated from the source to the target by a uniform electric field with a magnitude of about 100kN/C , as drawn in the figure above. When the electrons hit the target, x-rays are produced. (a) What is the potential difference between the electron source and the metallic target? (b)...
