Does the intensity of light mean increase no. of photons?
For a given frequency of photons it does. A maximum of one photoelectron for each arriving photon.cbram said:Does the intensity of light mean increase no. of photons?
cbram said:Then for instance if the light carries 21 photons per second then the next second also should carry the same amount of photons

The number of photons in the incident light determines the number of electrons that will be ejected from the metal surface in the photoelectric effect. The more photons that hit the surface, the more electrons will be emitted.
Yes, the number of photons can be controlled by changing the intensity of the incident light or by using filters to limit the wavelength of the light. This can affect the energy of the ejected electrons and the overall outcome of the photoelectric effect.
Yes, there is a minimum threshold frequency or energy required for the photoelectric effect to occur. This is determined by the work function of the metal, which is the minimum energy required to eject an electron from its surface. If the incident light does not have enough energy, the photoelectric effect will not occur.
The number of photons is directly proportional to the kinetic energy of the ejected electrons in the photoelectric effect. This means that increasing the number of photons will result in an increase in the kinetic energy of the electrons, as long as the frequency of the light remains above the threshold frequency.
Yes, the concept of the number of photons helps to explain the wave-particle duality of light in the photoelectric effect. On one hand, light behaves as a wave and its energy is dependent on its frequency. On the other hand, it also behaves as a particle, with each photon carrying a specific amount of energy. The number of photons can be used to calculate the total energy of the incident light and its effect on the ejected electrons.
