8. When a photoelectric surface is illuminated with light of wavelength 537 nm, the stopping potential ismeasured to be 1.67 V. (h = 6.626 x 10-34 J · s, 1 eV = 1.60 × 10-19 J, e = 1.60 x 10-19 C, melectron =9.11 x 10-31 kg, h = 6.626 x 10-34 J s)(a) What is the work function of the metal, in eV?(b) What is the maximum speed of the ejected electrons?(c) If the frequency of the illuminating light is changed to 9.98 x 1014 Hz, what will the new stoppingpotential be measured as?

We use the formula for photoelectric effect to get the required.
