    Question

    The wavelength of limiting line of Pfund series is:

    1. 2.2 cross times 10 to the power of negative 4 end exponent m    
    2. 2.2 cross times 10 to the power of negative 3 end exponent cm    
    3. 2.2 cross times 10 to the power of negative 6 end exponent cm    
    4. 2.2 cross times 10 to the power of negative 4 end exponent cm    

    The correct answer is: 2.2 cross times 10 to the power of negative 4 end exponent cm
