Students’ Misconception of Light Refraction about Real and Apparent Depth

This research objective to explore the misunderstandings of real and apparent depth of 49 grade 12 students. The researcher test to survey the understanding of the occurrence of images real and apparent depth, 3 items. It consists of answering questions by dragging a path of light from an object into the eye. Which covers 3 topics: image formation on real and apparent depth when the object is in the water and the observer is in the air, image formation when the object is in the water and change the position of the observer in the water surface. The study found that students had misconceptions about how the path of light from an object enters the eye to locate the real depth of the image, where the object was in the water and the observer was in the air above the water surface. If the object is in the water and changes the position of the observer and if the object is in the air and the observer is below the surface 83.7%, 24.5% and 8.2% respectively. The results of this study could lead to the development of learning management to resolve misunderstandings to understanding and need to learn.
