Emission of electrons in the photoelectric effect is possible, ifa) ...
Explanation:
Photoelectric effect is the phenomenon in which electrons are emitted from a metal surface when light falls on it. The following conditions must be satisfied for the emission of electrons in the photoelectric effect:
1. Metal surface:
The metal surface should be clean and free from any impurities. The surface should also be highly polished to minimize the loss of energy due to scattering.
2. Intensity of light:
The intensity of light should be sufficiently high to overcome the work function of the metal. The work function is the minimum energy required to remove an electron from the metal surface.
3. Angle of incidence:
The angle of incidence of light does not affect the emission of electrons in the photoelectric effect. However, if the light is incident at an angle, the number of electrons emitted per unit area decreases.
4. Wave length of light:
The wavelength of light is the most important factor affecting the emission of electrons in the photoelectric effect. The energy of a photon is directly proportional to its frequency and inversely proportional to its wavelength. Therefore, the higher the frequency of the light, the higher the energy of the photons. If the energy of the photons is less than the work function of the metal, no electrons will be emitted.
Therefore, the correct option is D, i.e., the incident light of sufficiently low wavelength. This is because the energy of the photons increases as the wavelength decreases. Therefore, if the wavelength of the light is sufficiently low, the energy of the photons will be high enough to overcome the work function of the metal and emit electrons.

The wavelength should be low because lower the wavelength higher the frequency and for photo electric effect to occur we need a threshold frequency.
