Given:
Dispersion
Required: To choose the correct option.
Explanation:
Reflection is the process when a light ray strikes a surface and returns back in the same medium.
Refraction is the process of bending light when light travels from one medium to another.
Monochromatic light is light that has only one color.
Polychromatic light is the light that constitutes multiple colors in the same source.
When dispersion occurs light travels from one medium to another, and it bends after entering the second medium.
As polychromatic has multiple colors and each color corresponds to a particular wavelength.
The bending of light also differs by wavelength, so each color will bend at different angles.
Final Answer: The dispersion occurs for polychromatic light in refraction.
