In an experiment on zinc, the straight-line graph of stopping potential V0 versus frequency ν has a slope of 4.11×10−15Vs and cuts the voltage axis at −2.40V.
a. Part 1: (i) Calculate the value of Planck’s constant h implied by the slope.
b. Part 2: (ii) Determine the threshold frequency for zinc.
c. Part 3: (iii) Find the work function of zinc in eV.
d. Part 4: (iv) For incident light of wavelength 200nm, calculate the maximum kinetic energy of the emitted photoelectrons and the corresponding stopping potential.
