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

Answer» Correct Answer - B 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. |
