FAQs on 25. Photoelectricc Effect - Theory Sheet, Class 12 Physics - JEE

1. What is the photoelectric effect?
Ans. The photoelectric effect refers to the phenomenon in which electrons are emitted from a material's surface when it is exposed to light or electromagnetic radiation.
2. How does the photoelectric effect support the particle nature of light?
Ans. The photoelectric effect supports the particle nature of light as it demonstrates that light is composed of discrete packets of energy called photons. Each photon interacts with an electron in the material, transferring its energy and causing the electron to be emitted.
3. What factors affect the photoelectric effect?
Ans. The photoelectric effect is influenced by several factors, including the intensity of the incident light, the frequency or energy of the light, and the characteristics of the material, such as its work function and the presence of a potential barrier.
4. What is the work function in the context of the photoelectric effect?
Ans. The work function refers to the minimum amount of energy required to remove an electron from the surface of a material. It is a characteristic property of the material and determines the threshold frequency or energy of the incident light required to cause the photoelectric effect.
5. How does the photoelectric effect explain the observation of different colors in a photoelectric experiment?
Ans. The photoelectric effect explains the observation of different colors by the fact that different colors of light have different frequencies and energies. Only light with a frequency or energy greater than the threshold value can cause electrons to be emitted. Hence, different colors of light with varying frequencies can result in different electron emissions, leading to the observation of different colors in a photoelectric experiment.
