If an x-ray machine were designed to operate at two separate accelerating voltages,one double the other,how would the shortest wavelength,ë_min,hv,and the maximum frequency,f_max,hv,at the higher voltage compare to those (ë_min,lv,f_max,lv)at the lower voltage? ë_min,hv/ ë_min,lv = ________,f_max,hv/ f_max,lv =________: A)2,2. B)2,1/2. C)1/2,2. D)1/2,1/2.
