Light, Reflection and Refraction

The aim of this lecture is to present on Light, Reflection and Refraction. Light is a complex phenomena. Its exact nature is not fully understood and this complexity makes it difficult for one model to describe all of light’s properties. As a result, different models describe different aspects of light’s behavior. The electromagnetic wave theory explains light’s ability to travel through a vacuum. The light ray model, on the other hand, can describe interactions between light and matter.
