Virtual Microscopic Simulation (VMS) design on light waves: Interference and diffraction

Abstract

The properties of light waves are only looking indirectly through physic phenomena, such as interference and diffraction of light. This causes light waves to become of the physics materials that are difficult for students to understand. This study aims to produce a Virtual Microscopic Simulation (VMS) design on light wave material. The research method used in this research is research and development using the ADDIE development model. However, the ADDIE development model used is only to Design stage. The instrument used to measure the feasibility of VMS media is a validation test by media and materials experts. The results showed that characteristics of VMS design in light waves consist of two topics, namely interference and diffraction of light. VMS has a positive impact on students in the physics learning, especially about microscopic materials. VMS expected to effective in helping students to understand the light wave material, especially about the concept of interference and diffraction of light.
