Photoelectric effect can be explained by assuming that light
Text Solution
Verified by ExpertsThe correct answer is:
D
Step 1: The photoelectric effect is a phenomenon where electrons are emitted from a material when it absorbs light of sufficient frequency.
Step 2: This effect was explained by Albert Einstein in 1905, who proposed that light consists of discrete packets of energy called 'photons' or 'quanta'.
Step 3: According to this theory, when a photon with energy greater than the work function of the material strikes an electron, it can impart enough energy to eject the electron from the material.
Step 4: This understanding led to the development of quantum theory, distinguishing light's particle-like properties from its wave-like properties.
Therefore, the correct answer is D.
