Prism Experiment
The first experiment of light passing through the prism was first conducted by the great scientist Newton. He allows white light to pass through a prism hoping to get white light to the other end. But to his surprise, he found that white light gets changed to the spectrum of the seven colours. He named this phenomenon as dispersion of light.
Through this experiment, he concluded that light is made up of a spectrum of light. To further prove his experiment he from some other tests as
- He allows the light of only one wavelength to pass through the prism and observes the light ray coming out of the prism and found that this ray only gets refracted and so no sign of dispersion.
- He realized that only white light shows dispersion, as it is made of several colours of light and all these colours of light, have different wavelengths thus their refraction is not the same they all get deviate differently passing through the prism and allowing to form the spectrum of light.
- He concludes that violet light has the shortest wavelength and hence it deviates most whereas red light has the highest wavelength and hence it deviates the least.
Dispersion of Light through a Prism
Dispersion of Light happens when white light is split into its constituent hues due to refraction. Dispersion of Light can be achieved through various means but the most common way to achieve dispersion of light is through Prism. Dispersion of light by a prism results in the breaking of white light into its seven constituents.
Dispersion of Light through a prism is achieved by allowing the white light to fall on the prism and passing the light through the prism to break it into its constituent colours. In this article, we will learn about the Dispersion of Light, its experiment and others in detail.
