JEE AdvancedPhysicsDual Nature of RadiationMCQ+3 / −1
A metal target with atomic number Z=46Z=46Z=46 is bombarded with a high energy electron beam. The emission of X-rays from the target is analyzed. The ratio rrr of the wavelengths of the KαK_\alphaKα​-line and the cut-off is found to be r=2r=2r=2. If the same electron beam bombards another metal target with Z=41Z=41Z=41, the value of rrr will be
