Electrons with energy 80 ke V are incident on the tungsten
target of on X-ray tube. K-shell electrons of tungsten have 72.5 ke V energy.
X-ray emitted by the tube contain only
(a) a continuous X-ray spectrum (Bremsstrahlung) with a minimum wavelength of
`~~ 0.155Å`. (b) a continuos X-ray spectrum (Bremsstrahlung) with all wavelegths
(c ) the characteristic X-ray spectrum of tungsten
(d) a continuous X-ray spectrum (Bremsstrahlung) witha minimum wavelength of
`~~ 0.155 Å` and the characteristic X-ray spectrum of tungsten.
