A student performs a photoelectric experiment in which light of various frequencies is incident on a photosensitive metal plate. This plate, a second metal plate, and a power supply are connected in a circuit, which also contains two meters, M1 and M2, as shown above (see attachment, #1).
The student shines light of a specific wavelength λ onto the plate. The voltage on the power supply is then adjusted until there is no more current in the circuit, and this voltage is recorded as the stopping potential V_s. The student then repeats the experiment several more times with different wavelengths of light. The data, along with other values calculated from it are recorded in the table (attachment, #2).

a.) indicate which meter is used as an ammeter and which meter is used as a voltmeter by checking the appropriate spaces: Ammeter for M1 and M2, Voltmeter for M1 and M2.

b.) Use the data above to plot a graph of Kmax versus f on the zxes below, and sketch a best-fit line through the data. (graph in attachment, too)

c.) Use the best fit line from (b) to calculate an experimental value for Planck's constant.

2. In the photoelectriceffect experiment, light photons strike a photoelectric material in a phototube and electrons are emitted with a certain kinetic energy. If the stopping energy of the electrons is graphed as a function of the frequency of light, then the slope of the line will be Planck's constant

Ultraviolet light is incident normally on the surface of a certain substance. The binding energy of the electrons in this substance is 3.44 eV. The incident light has an intensity of 0.055 W/m2.

The work function of an element is the energy required to remove an electron from the surface of the solid. The work function for cadmium is 378.2 kJ/mol (that is, it takes 378.2 kJ of energy to remove 1 mol of electrons from 1 mol of Cd atoms on the surface of a sample of cadmium.) What is the maximum wavelength of light that c

Planck's formula for spectral distribution of the flux emitted by a blackbody is:
