Photoelectron ejection is important in technological applications. Recently, the photoelectric effect was explained based on the electromagnetic (EM) wave concept. According to the EM wave concept, an electron within the conduction band of a photocell moves circularly. In this paper, we explain few facts regarding the photoelectric emission process, such as the radius of circular motion, maximum ejection angle, and depth of the photoelectron, based on the EM wave concept. Further, the effects of the intensity and frequency on these parameters are discussed. The ejection angle depends on the frequency and intensity of the light and the depth of the photoelectrons. The explanations herein may increase the applications of light energy.

光电子射出在技术应用中很重要。最近，基于电磁（EM）波概念解释了光电效应。根据 EM 波的概念，光电池导带内的电子作圆周运动。在本文中，我们基于电磁波概念解释了有关光电发射过程的一些事实，例如圆周运动半径、最大喷射角和光电子的深度。此外，还讨论了强度和频率对这些参数的影响。射出角取决于光的频率和强度以及光电子的深度。这里的解释可以增加光能的应用。
