describe dispersion of white light. what do different colours of light bend to different extents when passed through a prism ?
Answers
Explanation:
As a result, when white light passes through the refracting surface of the prism, its components bend into different angles, causing the single beam of light to separate. Then, the different colors of light bend again because of the refraction caused by the second rectangular surface.
Answer:
The phenomenon of splitting of white light into its constituent colours is called dispersion. When white light is allowed to pass through a prism, it splits into a band of seven colours-violet, indigo, blue, green, yellow, orange and red (VIBGYOR). Dispersion of light occurs because different colours of light bend to different extents when passed through a prism.
This is because the refractive index of a medium with respect to another medium is different for different colours. Red colour deviates (or bends) the least, whereas violet deviates the most. This is why red forms the top band of the spectrum and violet forms the bottom band.
