![]() Light disperses and creates a rainbow effect, when it propagates and refracts in a prism.The splitting of white light into its constituent colours is called dispersion of light.The angle between the directions of the incident ray and that of the emergent ray is called the angle of deviation and is represented by Greek letter δ or q d. The angle between the normal and the refracted ray is known as the angle of refraction. The angle formed between the incident ray and the normal at the point of incidence is known as the angle of incidence. The ray that deviates at the point of incidence due to a change in the medium is the refracted ray. The angle between two refracting surfaces of a triangular glass prism is denoted by A, called the angle of the prism or the refracting angle. Any two rectangular faces are the refracting surfaces and the third one is the base. It is a solid structure having three rectangular and two triangular surfaces. This phenomenon can be observed in a lab environment using a triangular glass prism. The wavelength of each colour is different that causes the difference in velocity of the corresponding light when passing from one medium to another. The cause of dispersion is that sun light consists of seven constituents (colours namely violet, indigo, blue, green, yellow, orange and red popularly referred to as VIBGYOR) that have different refractive index with respect to a medium.
