An on-limits Optic experiment simulation software for teachers and students of high school in physics education.Special to other common CAI software of physicseducation,'Jslsoft Optic Lab' is not simply to displaysome ready-made experiment in computer,It provides aexperiment environment filled with opticinstrument,you can make optics experiment which youdesign by yourself freely. 'Jslsoft Optic Lab'provides optic instruments such as quadratemedium,triangle medium(prism),ideal diverginglens,ideal converging lens,convex mirror,concavemirror,plane mirror,light and so on. With thisinstrument,you can easy to make some experiment likereflection of mirrors,refraction of medium,dispersionof prism,whole reflection of medium,converging ordiverging of lens and so on.The software can displaythe whole physics proceed specially for you. it is auseful physics education tool currently.
