The correct sequence of energy transformation in the operation of an x-ray tube is i. X-rays ii. Kinetic energy of thermo electrons iii. Potential energy of the target atoms iv. Heat energy of the emitted electrons
A
iv, iii, ii, i
B
ii, iv, iii, i
C
iv, ii, iii, i
D
iii, iv, ii, i
Verified Correct Answer: C.
Physical Principles & Numerical Solution
X–rays are a stream of particles that are emitted when fast accelerating or moving electrons collide with a tungsten target. X-rays are produced when electrons produced by thermionic emission are accelerated through high voltage and are focused onto a tungsten target. The accelerated electrons strike the tungsten target, transform into heat, and emit radiation called x-rays. So the correct sequence of energy transformation in the operation of an X-ray tube is Option C.
