An X ray tube is operated at a tube potential of 40,000 V. Calculate :
(i) Kinetic energy of an electron emitted by the filament when it reaches the target / anode.
(ii) Wavelengths of all the X rays emitted by the X ray tube.
(i)
Mass of reactants = 2.015 x 2
= 4.030z
Mass of products = 3.017 + 1.009
= 4.026M
Mass defect sin = 0.004u.
We know 1 u = 931 MeV.
So,
Energy Released = 0.004 x 931
= 3.724 MeV. Ans.
(ii) Fusion Reaction
What is meant by the terms :
(i) a full wave rectifier ?
(ii) an amplifier ?
(iii) an oscillator ?
