which of the following statement about `x`rays is false?A. `E(K_(alpha))+E(L_(beta))+E(M_(alpha))=E(K_(gamma))` where E is the energy of respective `x`-raysB. for the harder `x`-rays the intensity is higher then soft `x`-raysC. the continous and characteristic `x`-rays differ only in the method of creationD. the cut-off wavelength lambda_(min) depend only on the acceleration voltage applied between the target and the filament. |
Answer» Correct Answer - B Penetrating power of hard `x`-rays is more than soft `x`-rays and penetrating power depends on frequency but not on intensity. |
