Question

why do white light disperses through prism​

Answer 1

${\huge{\underline{\bold{ \purple{\tt{Answer}}}}}}$

☞The velocity of light in a material medium depends upon this color (wavelength) i.e. the refractive index of a material is different for different colors.

☞If we incident a ray of white light on a prism; on emerging, the different colors are deviated through different angles.

☞ Due to this, white light splits into its constituent colors and the phenomenon is called dispersion.

Answer 2

Answer:

Since different colors of light travel at different speeds, the refractive index is different for each color. 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.
