Question

The variation of wavelength lambda of the K subscript alpha end subscript line with atomic number Z of the target is shown by the following curve of

  1. A    
  2. B    
  3. C    
  4. None of these    

The correct answer is: C


    For Kaline nu proportional to left parenthesis Z minus 1 right parenthesis to the power of 2 end exponent Þ lambda proportional to fraction numerator 1 over denominator left parenthesis Z minus 1 right parenthesis to the power of 2 end exponent end fraction
    i.e. the graph between l and z will be (c).
