D)the frequency of radiation
E)none of the above

Question

Quizplus · Accepted Answer

A point in the wave function where the amplitude is zero is called a node. This is because at that point, the probability of finding the particle is zero. The excited state (B) refers to a state where the electron is in a higher energy state than its ground state. The amplitude of the wave function (C) refers to the height of the wave at a particular point. The frequency of radiation (D) refers to the number of cycles of the wave that pass a point in a unit of time. None of these concepts relate to a point in the wave function where the amplitude is zero.
