Question
50% of the X-rays coming from a Coolidge tube is able to pass through a 0.1 mm thick aluminum foil. The potential difference between the target and the filament is increased. The thickness of aluminimum foil, which will allow 50% of the X-ray to pass through, will be -
Options
A.zero
B.< 0.1 mm
C.0.1 mm
D.> 0.1 mm
Solution
With increase of potential difference, x-ray of higher energy will be produced. To stop them, thicker foil is required.
