The inclined refracting surfaces of a glass prism exhibit the phenomenon of dispersion, where white light is separated into its component colors. The activity involves observing this phenomenon by allowing light to pass through the prism, revealing the different colors ...

The refraction of light through a prism plays a crucial role in the formation of a rainbow. When sunlight enters raindrops, it undergoes both reflection and refraction. The refraction, particularly through the spherical shape of raindrops, causes the dispersion of ...

The various colors in a rainbow are produced by the dispersion of white light from the Sun. When white light passes through raindrops, it undergoes dispersion, separating into its component colors due to their different wavelengths.

The angle of deviation is represented by ÐD in the diagram. It is the angle between the direction of the incident ray and the direction of the emergent ray after passing through the prism.

The angle formed between the incident ray and the emergent ray in a prism is known as the angle of deviation.
