1.	From the figure describing photoelectric effect we may infer correctly that A. Na and Al bothh have the same threshold frequencyB. maximum kinetic energy for both the metals depend linearly on the frequencyC. the stopping potential are different for Na annd Al for the samme change in frequencyD. Al is a better photo sensitive material than Na
Answer» Correct Answer - B The graph betweenn stopping potential and frequency is a straight line, so stopping potential and hence, maximum kinetic energy of photoelectrons depends linearly on the frequency.
