Which consequence results when high-energy electrons bombard a tungsten anode?

A)Characteristic X-ray emission predominates.
B)Increased electron pair production occurs.
C)High-energy beta decay initiates.
D)Anode temperature decreases asymptotically.

💡 Explanation

Characteristic X-ray emission results from electron transitions within tungsten atoms when bombarded by high-energy electrons, because inner-shell electrons are ejected via inelastic scattering, followed by other electrons filling the vacancies during relaxation. Therefore, we see X-rays, rather than beta decay, through *fluorescence*.
