1 3. v1 V2 λ n1 n2 n3 Metal A Metal B Metal C Three light beams with identical wavelengths but different photon fluxes (photons per second) are incident on three different metals, as shown above. The relationship of the light beams to number of photoelectrons per second is: n, =n2 < ng. The relationship of the light beams to the maximum speed of the photoelectrons is: v1 > V2 > V3. Which metal has the largest work function? metal C metal A metal B All three have the same work function.

You have a sample of Sodium with a Work Function of 2.28 eV that you are shining light upon to demonstrate the Photoelectric Effect. Which type of light would be the lowest Energy that would still work? [If visible light, state the color.] How fast will an electron be ejected from the sample material if we use UV light of wavelength of 10.0 nm? m/s

Photoelectric effect is observed on two metal surfaces. Light of wavelength 300.0 nm is incident on a metal that has a work function of 2.40 eV. What is the maximum speed of the emitted electrons? m/s

A beam of 400 nm light is adjusted to have the same intensity as a beam of 600 nm light. How does the number of photons in the 400nm beam, N400 compare to the number of photons, N600 in the 600 nm beam.   Question 5 options:   N400 = 2*N600   N400 = 32600   N400 = N600   N400 = 23600   N400 = 2600   None of the other responses are correct.
