What is dispersion of light?
Answers
Dispersion of light is the phenomenon of splitting of white light into its constituent colours. Sun emits electromagnetic waves, which have a wide range of wavelengths. The arrangement of the waves in the order of their wavelengths is called electromagnetic spectrum. The waves with wavelengths, which fall in the visible region of the spectrum is light.
Hence, light consists of electromagnetic waves of different wavelengths. Each wavelength imparts a specific colour. The spectrum of the visible light is called VIBGYOR.
Answer:
When white light is passed through a glass prism it splits into its spectrum of colours (in order violet, indigo, blue, green, yellow, orange and red) and this process of white light splitting into its constituent colours is termed as dispersion. The simplest way to explain dispersion is through dispersion in the prism.
