5. A researcher is interested in determining an unknown metal using the photoelectric effect. When the researcher shines x nm of light onto the metal, no electrons are observed to be ejected. When the wavelength is halved (x/2 nm), electrons are observed to be ejected from the sample. Which one of the following statements must be true? A. The frequency threshold must be 2c/x for the unknown metal. B. The momentum of the ejected electrons has decreased. C. The Ebinding of the unknown metal is 2hc/x. D. The Elight is greater than Ebinding when the researcher halved the wavelength of the photons.
