X-ray from a tube with a target A of atomic number Z shows strong K lines for target A and weak K lines for impurities. The wavelength og K_(alpha) lines is lambda_(z) for target A and lambda_(1) and lambda_(2) for two impurities. (lambda_(z))/(lambda_(1)) = 4 and (lambda_(z))/(lambda_(2)) = (1)/(4) Assuming the screeining contant of K_(alpha) lines to be unity select the correct statement(s).
