Vedclass · Answer

(D) The peaks at $R$ and $S$ represent the characteristic $X$-ray spectrum.These peaks correspond to specific energy transitions of electrons within the atoms of the target material. Since these energy levels are intrinsic to the target material,the wavelengths of the characteristic peaks remain unchanged when the accelerating potential difference is varied.The point $P$ represents the cut-off wavelength,${\lambda _{\min }}$,which is given by the relation ${\lambda _{\min }} = \frac{hc}{eV}$.As the accelerating potential difference $V$ increases,the cut-off wavelength ${\lambda _{\min }}$ decreases,meaning the graph shifts towards the left at point $P$.
