Question
Albert Einstein used corpuscular theory to explain:

Answer

  1. The photoelectric effect
Explanation:
The photoelectric effect.
In 1905, Albert Einstein published a paper in advancing hypothesis that the light energy I'd being carried in discrete quantized packets to explain experimental data from photoelectric effect. This model contributed the development of quantum mechanics.
Photoelectric effect refers to the emission, or rejection of electrons grim the surface of generally a metal in response to the incident light.
