The ratio of wavelengths of K_alpha-characteristic X-rays produced when iron (Z = 26) and scandium ( — Atomic Structure Chemistry Question
Question
The ratio of wavelengths of K_alpha-characteristic X-rays produced when iron (Z = 26) and scandium (Z = 21) are used as anticathode, is
Answer: C
💡 Solution & Explanation
Moseley's law: 1/λ ∝ (Z-1)^2. lambda_Fe/lambda_Sc = [(21-1)/(26-1)]^2 = (20/25)^2 = 16:25.
