light after passing through glass​

Answer 1

Answer:

B.) the splitting of a beam of light into component colours

Answer 2

Dispersion is the term used to describe B. the splitting of a beam of light into  component colours.

What is dispersion?

• Dispersion is the wave property of light.
• It refers to the separation of light rays into its different components.
• White light consists of seven visible wavelengths ranging from violet to red.
• Violet has the least wavelength and maximum frequency among all the visible colours.
• Red has the maximum wavelength and least frequency among all the visible  colours.
• The white light gets dispersed into all the visible wavelength called spectrum.
• This spectrum of wavelength ranges from 400 nm to 700 nm.
