Final answer:
The concept of work function or binding energy is not in line with the classical wave model; it is a quantum mechanical concept that requires energy quantization, which the classical model does not provide. Hence, the statement is false.
Step-by-step explanation:
The concept of a work function or binding energy is not permissible under the classical wave model. According to the classical wave model, energy can be absorbed or emitted in any amount; this is in contrast to the quantum model introduced by Max Planck and Albert Einstein, which suggests that energy is absorbed or released in discrete quantities known as quanta. The classical wave model does not account for this aspect of quantization. The work function is a quantum mechanical concept and refers to the minimum energy required to remove an electron from a solid to a point immediately outside the solid surface. Therefore, the statement that a work function (or binding energy) is permissible under the classical wave model is false.
