The correct answers to explain the results of a photoelectric effect experiment according to quantum physics are:

a. Light energy is quantised (in the form of photons) b. Electron energies are quantised into levels d. Electrons can interact with photons only on an all or nothing basis

Explanation:

a. In the photoelectric effect, light energy is absorbed by electrons in a material. Quantum physics suggests that this energy is quantised, meaning it comes in discrete amounts, called photons.

b. Quantum physics also suggests that the energies of electrons in a material are quantised into specific levels. This means that an electron can only exist at certain energy levels and cannot exist in between these levels.

d. The interaction between electrons and photons is an all or nothing event. This means that an electron can only absorb a photon if the energy of the photon matches the energy difference between the electron's current energy level and a higher one. If the photon's energy is not enough to move the electron to a higher energy level, the photon will not be absorbed.
