The photoelectric experiment, conducted by Albert Einstein, demonstrated that light can behave as both a particle (photon) and a wave. It showed that the energy of photons is directly proportional to their frequency, not their intensity. This supported the quantum theory of light and was pivotal in the development of modern physics.
Albert Einstein's most famous experiment was the photoelectric effect experiment, which helped confirm the particle nature of light and contributed to the development of quantum theory.
The stopping potential formula is V hf/e, where V is the stopping potential, h is the Planck constant, f is the frequency of the incident light, and e is the elementary charge. This formula is used to calculate the minimum voltage needed to stop the emission of electrons in a photoelectric experiment.
Photoelectric measurements are sensitive to the nature of the photoelectric surface because the surface properties, like work function and reflectivity, directly affect the efficiency of electron emission when photons are absorbed. The surface characteristics influence the energy required for electron liberation, impacting the overall photoelectric effect.
why are photoelectric measurements are so sensitive to the nature of the photoelectric surface
The photoelectric effect experiment demonstrated that electrons are emitted from a material when it is exposed to light of a certain frequency, regardless of the light's intensity. This discovery contributed to the development of quantum theory and helped support the idea that light behaves as both a wave and a particle.
The science teacher alerted the students, then, continued to demostrate the experiment.

Switching to a brighter light source. Switch to a light source with a higher intensity.
Increasing the intensity of light or using a shorter wavelength light source can cause an electric current to flow in a photoelectric effect experiment. The energy of the photons should be increased to overcome the work function of the metal surface, allowing electrons to be ejected and generate a current.
