Solution

The correct option is D Accelerating voltage.
Energy with which the X rays are generated (electrons) are dependent on the accelerating voltage.
And the energy depends on cutoff wavelength of the X rays.

Q. The figure shows the intensity-wavelength relations of X-rays coming from two different Coolidge tubes. The solid curve represents the relation for the tube A in which the potential difference between the target and the filament is V_A and the atomic number of the target material is Z_A. These quantities are V_B and Z_B for the other tube. Then,
(a) V_A > V_B, Z_A > Z_B
(b) V_A > V_B, Z_A < Z_B
(c) V_A < V_B, Z_A > Z_B
(d) V_A > V_B, Z_A < Z_B

Q. 50% of the X-ray coming from a Coolidge tube is able to pass through a 0.1 mm thick aluminium foil. If the potential difference between the target and the filament is increased, the fraction of the X-ray passing through the same foil will be:
