The graph between 
and stopping potential V of three metals having work function φ 1 , φ 2 and φ 3 in an experiment of photo-electric effect is plotted as shown in the figure. Which of the following statements is/are correct.
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(b, c, d)
From graph φ 1 : φ 2 : φ 3 = 1 : 2 : 4
therefore λ 1 : λ 2 : λ 3 = 4 : 2 : 1
slope = 
= constant, does not depend on the metal.
