The tube in a medical research X-ray unit uses lead (Z=82) as it's target. 1) Use the Bohr model to estimate the minimum kinetic energy electrons must have to in order for Kα X-rays to just appear in the X-ray spectrum of the tube. Ee = 2) Assuming the electrons are accelerated from rest through a voltage, V, what is the minimum voltage necessary to produce the Kα X-rays?
