A photon can transfer its energy into an electron, it was first explained by
Correct answer: C. Einstein
- A. Maxwell
- B. Hertz
- C. Einstein
- D. Bohr
Explanation
The scientist who first explained how a photon can transfer its energy into an electron was Albert Einstein. In his 1905 paper on the photoelectric effect, Einstein proposed that light is not a wave, but rather a stream of particles called photons.

About Photons and the Particle Model of Light
The particle model treats light as photons with energy E equals hf and momentum related to wavelength. Questions involve the photoelectric effect, work function, threshold frequency, stopping potential and photon energy, while distinguishing particle behaviour from the wave description of interference and diffraction.
