Question

A beam of electrons striking a copper target produces X-rays. Its spectrum is as shown. Keeping the voltage same if the copper target is replaced with a different metal, the cut-off wavelength and characteristic lines of the new spectrum will change in comparison with old as, Cut-off wavelength will remain unchanged while characteristic lines will be different, Both cut-off wavelength and characteristic lines will remain unchanged, Both cut-off wavelength and characteristic lines will be different, Cut-off wavelength will be different while characteristic lines will remain unchanged

MARKS App · Accepted Answer

Cut- off wavelength of emitted X-rays depends on maximum kinetic energy of incident electrons on the target and is independent of nature of target. The characteristic lines depend on nature of material of target.
