Question

The wavelength of the K α line for an element of atomic number 43 is λ . Then the wavelength of the K α line for an element of atomic number 29 is, 43 29 λ, 42 28 λ, 9 4 λ, 4 9 λ

MARKS App · Accepted Answer

ν ∝ ( Z - 1 ) 2 or c λ ∝ ( Z - 1 ) 2 For atomic number 43 1 λ ∝ ( 43 - 1 ) 2 For atomic number 29 1 λ 1 ∝ ( 29 - 1 ) 2 So λ 1 = ( 42 ) 2 ( 28 ) 2 × λ = 9 4 λ .
