Lithium was one of the metals studied by the American physicist Robert Millikan in his research on the photoelectric effect. When illuminated with blue light of frequency 6.64 x 10" Hz, the photoelectrons ejected from a lithium surface have a maximum kinetic energy of 0.332 eV. What is the threshold frequency for lithium? For this problem, let the value of Planck's constant, h, be 6.63 x 10J's

Athin, square metal plate measures 14 cm on each side and has emissivity of 0.60. the plate is heated to a temperature of 745Β°c. what is the rate at which the plate radiates energy ? the stefan-boltzmann constant is 5.67 Γ 10-8 w/(m2 ? k4). remember that the plate will radiate energy from both its top and bottom surfaces.
