Explanation:
The photoelectric effect is the emission of electrons from a metal surface when it is exposed to light. The electrons are emitted when photons of light strike the metal surface and transfer their energy to the electrons.
The condition required for the emission of electrons in the photoelectric effect is the minimum energy required for the photons to transfer their energy to the electrons, which is given by the equation E=hf, where E is the energy of the photon, h is Planck's constant, and f is the frequency of the light.
Therefore, the correct option is D, i.e., the incident light of sufficiently low wavelength. This is because the energy of a photon is inversely proportional to its wavelength. Hence, the shorter the wavelength of the incident light, the higher the energy of the photons, and the easier it is for them to transfer their energy to the electrons.
The other options are not correct because:
- Option A: The surface of the metal does not have to be highly polished for the photoelectric effect to occur.
- Option B: The intensity of the incident light does not affect the energy of the photons, and hence, is not a condition for the photoelectric effect.
- Option C: The angle of incidence of the light does not affect the energy of the photons, and hence, is not a condition for the photoelectric effect.

Every metal moreover every substance have a particular workfunction i.e they need a particular energy for the emission of electron so to provide that energy we have to incident photons with sufficiently low wave length which is known as threshold wavelength .
