A) 0.940 K
B) 1.10 K
C) 1.26 K
D) 2.78 K
E) 3.78 K
Question 2
A photoelectric surface has a work function of 2.10 eV.
Calculate the maximum kinetic energy, in eV, of electrons ejected from this surface by electromagnetic radiation of wavelength 356 nm. (1 eV = 1.60 10-19 J, c = 3.00 108 m/s, h = 6.626 10-34 J s)
