An X-ray tube has three main controls.
(i). The target material (its atomic number Z)
(ii). The filament current `(l_(f))` and
(iii). The accelerating voltage (V)
Figure shown a typical intensity distribution against wavelength which of the following si incorrect?

Options

A. The limit `lamda_(min)` is proportional to `V^(-1)`
B. The sharp peak shifts to the right as Z is increased
C. The penetrating power of X ray increases if V is increased
D. The intensity everywhere increases if filament current `l_(f)` is increased

Answer

B

Explanation

As accelerating voltage is increased, energy increases, the `lamda_(min)` decreases and X-rays are getting harder (less wavelength) and penetrating power increases if filament current increases, more electrons are emitted.
