	\section{Introduction}
	
	Optics is the study of light and its interaction with matter. Light can be described as both a wave and a particle.
	
	\section{Reflection}
	
	Reflection occurs when light bounces off a surface, with the angle of incidence equaling the angle of reflection.
	
	\section{Refraction}
	
	Refraction is the bending of light as it passes from one medium to another with a different refractive index. Refraction is the bending of light as it passes from one medium to another with a different refractive index.
