A new technique to teach basic concepts of refraction and reflection of light

Abstract

Nature of light is a facinating subject of education and training for children. However, it is not easy to demonstrate and explain fundamental properties of the light to the primary & secondary school students. In this paper, we will present a new technique to teach concept of refraction, reflection, and total internal reflection of light in glasses by utilizing deviation angles of a prism for various surrounding index-matching oils. © ETOP 2009.
