TEST YOUR UNDERSTANDING OF SECTION 38.2 In the apparatus shown in Fig. 38.7, suppose yau increase the number of electrons that are emitted from the cathode per second while keeping the potential difference VAc the same. How will this affect the intensity I and minimum wavelength Amin Of the emitted x rays? (i) I and dmin will both increase; (ii) I will increase but Amin will be unchanged; (iii) I will increase but Amin will decrease; (iv) I will remain the same but Amin will decrease; (v) none of these. I
