Analysis of the Level of Understanding of Physics Education Students on the Concept of Visible Light on Electromagnetic Wave Spectrum Material Using Descriptive Method

Abstract

The electromagnetic wave spectrum is electromagnetic radiation sequentially and indicates the type of wave based on frequency and wavelength. One type of electromagnetic wave spectrum is visible light. On the concept of physics of matter the spectrum of electromagnetic waves is very important to study because itsera is closely related in life.  This study aims to determine the level of students' understanding of the concept of visible light on the electromagnetic wave spectrum material. This research was conducted through a survey with respondents of physics education students. The sample used was 46 physics education students at the University of Jember. Data analysis uses a descriptive methodin the form of persentase. Based on the results of the study, it showed that the average score obtainedby students in physics education was 67.61. Thus, physics education students' understanding of the concept of visible light on the electromagnetic wave spectrum is quite good.
