Due to a change in potential, the electrons gradually changing in the number reflects that the ejected electrons possess a variety of velocities. For a negative potential of the collector, the current is reduced to zero indicating that is some upper limit of the energy that electrons emit.

On the other hand, the interference of electrons and the stability of an atom could only be described if electrons were considered as waves.

Classical physics failed to explain the experimental results of black body radiation, photoelectric effect, and the phenomena of interference of electrons, the stability of an atom. Classical physics considers waves and particles as different notions.

Einstein introduced the idea of “spacetime”. A massive object can wrap the fabric of spacetime and gravity is its consequence. Einstein also realized that mass and energy are equivalent concepts. The equivalent energy E corresponding to a mass m is, E = m c 2. Here, c denotes the speed of light in vacuum.
