When electron strikes with Al plate which photon is emitted?
Correct answer: D. None of these
- A. Blue
- B. White
- C. Purple
- D. None of these
Explanation
When light with a sufficiently high-frequency shine on a metal plate like aluminum, electrons are ejected from the plate. This factor is known as the Photoelectric effect. the electrons ejected in this process are called photo electrons

About Dawn of Modern Physics
Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.
