X-Ray Spectra:- X-rays frequeney. are EM radiations of High Hare Pare Their frequeny lies b/w V-ray & UV rays. Wavelength range: 0.1 to 100mm (0.1 to 10mm) ← I to 100 A Wavelength of X-rays, λ= ev ho C 1.24×10-6 1.24Mm 12400Å m= Min V V vis accelerating voltage. Types of X-ray spectruon:- 1. Continuous spectrum 2. Characteristic spectrum. 1. Continuous spectrum⇒ X-ray radiation giver Continuous spectrum whose intensity distribution in wavelength depends on the Incident electron energy (tube voltage) 2. Characteristic #spectrum:- This spectrum will have distinct spectral lines whose frequencies or wavelength are Characteristic of the material of the target. This line spectrum is called the X-ray spectrum of the material of the target. most elemest show in their xamy spectra two series of lines known as KQL-Seriep. The K-series is analogous to Lyman seriex of Hydrogen atorm. & The L-series is analogous to Balmer series of Hatom. K-series Contains a small no. of lines designated as Ka, Κβ, Κν Where- K2: Transition from n=2 ton=1 (K-shell) Κρ n=3ton=1 (K-shey) Kv n=4ton=1 (K-shell) Ex. The wavelength of ka line of Copper is 1.54 A The Wavelength of ka line of edits 0.54 A L-Series Contams a cdesignated as La, LB LY small no. of lines Where- La: Transition from n=3 to n = 2 (L-shell) Lp: n=4to n=2 (L-shell) LV: n=5 to n=2 (L-shell The K-series is analogous to Lyman seriex of Hydrogen atorm. & The L-series is analogous to Balmer series of Hatom.
