X-Ray Tube Parts, Intensity Control, and Heat Generation
Figure shows the features of an X- ray tube
(i) Name the parts labelled A and B.
A -
B -
(ii) Explain how a change in the potential across P changes the intensity of the X- rays produced in the tube.
(iii) During the operation of the tube, the target becomes very hot. Explain how this heat is caused.

(i)
A = Cathode rays / fast moving electrons
B = Anode
(ii) Change in heating current changes the number of electrons produced
(iii) Kinetic energyΔ1 of cathode rays is converted to heat
In this thought-provoking response, the author's perspective is skillfully backed by an extensive body of comprehensive research and readily available information, offering a well-informed and compelling exploration of the subject matter.
Identify radiation B and provide an explanation for the differing deviations observed in the paths of radiations A and C as they pass through an electric field, as depicted in figure 15.
Determine the frequency of X-rays produced in an X-ray tube with a 12000V acceleration voltage, assuming full energy conversion, using Planck's constant and the charge of an electron.
