Question 1 (1 point) Saved A proton and an electron both have kinetic energy E = 1 keV. What is the relationship between their de Broglie wavelengths? The are the same The proton has a longer de Broglie wavelength The proton has a shorter de Broglie wavelength There is insufficient information given to calculate the de Broglie wavelengths Question 2 (1 point) Saved The work function for a metal is 4:26 eV. What is the longest wavelength of light capable of freeing electrons from the metal's surface? 56.3 nm C 185 nm 291 nm 402 nmQuestion 3 {1 point) Saved Which one of the following statements concerning the photoelectric effect is false? (\"I In order to produce a current. the frequency of the incident light must be above \\_/ the threshold frequency f0 of the metal. (\"I If no current is produced at a given light intensity, a doubling of the light \\_./ intensity will still produce no current. as Assuming a current is produced, the amount of current is independent of the \\_/ intensity of the incident light. (\"I Assuming the frequency is above the threshold frequency. increasing the \\_/ frequency of the light will increase the kinetic energy of the ejected electrons.
