The graph between \( 1 / \lambda \) and stopping potential \( (V) \) of three metals having work functions \( \phi_{1}, \phi_{2} \) and \( \phi_{3} \) in an experiment of photoelectric effect is plotted as shown in the figure. Which of the following option(s) is/are correct? (Here, \( \lambda \) is the wavelength of the incident ray)
(a) Ratio of work function \( \phi_{1}: \phi_{2}: \phi_{3}=1: 2: 4 \)
(b) Ratio of work function \( \phi_{1}: \phi_{2}: \phi_{3}=4: 2: 1 \)
(c) \( \tan \theta \) is directly proportional to \( h c / e \), where \( h \) is Planck's constant and \( c \) is the speed of light
(d) The violet colour light can eject photoelectrons from metals 2 and 3 .
