Electrons with de-Broglie wavelength lamda fall on the target in an X-ray tube. The cut-off wavelength of the emitted X-rays is: |

Answer» `lamda_(0)=(2mclamda^(2))/(h)` `LAMBDA=(h)/(p)=(h)/(sqrt(2mK))` `or K=(h^(2))/(2mlambda^(2))` CUT of wavlength of X-ray is RELATED to K.E. as `(hc)/(lambda_(0))=K=(h^(2))/(2mlambda^(2))` `rArr lambda_(0)=(2mclambda^(2))/(h)` |
