Idk how to solve the last part if someone is there please help me
a graph between frequency (1) vs maximum kinetic energy (Ekmax) Sheet TAN ABE 2 1 Model Graph Energy of electrons vs frequency of light (for photoelectric cell) x-intercept is threshold frequency gradient = the Planck constant y-intercept is work function frequency (10514 Hz] 10 - Use Graph
II) Calculate the Percentage error for the following: Theoretical value of work function: a) Sodium b) Zinc c) Calcium d) Copper e) Platinum Parameter = 2.28 eV. = 4.3 eV = 2.9 eV = 4.7 eV = 6.35 eV Planck's Constant (h) Work function of Theoretical Value Experimental Value from the graph 6.63 x 10-34 J.S % of Error
