Question

why do different components of white light split up into spectrum when it passes through a triangular glass prism​

Answer 1

(ii) When a beam of light enters a prism, it gets refracted and splits into its seven constituent colours. This splitting of the light ray occurs because of the different angles of bending of each colour. ... This can be usedto separate a beam of white light intoits constituent spectrum of colors.

Answer 2

Different components of white light split up into spectrum when it passes through a triangular glass prism because:

• At the point when a light emission enters a crystal of prism, it gets refracted and parts into its seven constituent tones. This is called dispersion.
• This parting of the light beam happens on account of the various points of bowing of each tone.
• Consequently, each shading going through the crystal twists at various points with the regard to the occurrence bar.
• Violet has the shortest wavelength and is the most deviated, while Red has the longest wavelength and is the least distorted.
