Refractive index of any pair of media is inversely proportional to wavelength of light.
Hence,

λ_{v} < λ_{r}

\Rightarrow μ_{v} > μ_{r}

where,

λ_{v}

and

λ_{r}

are the wavelengths of violet and red light and

μ_{r}

and

μ_{v}

are refractive index of violet and red light.

Refractive index of any pair of media is inversely proportional to wavelength of light. Hence, λv​<λr​ ⇒μv​>μr​ where, λv​ and λr​ are the wavelengths of violet and red light and μr​ and μv​ are refractive index of violet and red light.

Q. Assertion Refractive index of glass with respect to air is different for red light and violet light.
Reason Refractive index of a pair of media depends on the wavelength of light used.

Refractive index of any pair of media is inversely proportional to wavelength of light.
Hence, $λ_{v} < λ_{r}$
$\Rightarrow μ_{v} > μ_{r}$
where, $λ_{v}$ and $λ_{r}$ are the wavelengths of violet and red light and $μ_{r}$ and $μ_{v}$ are refractive index of violet and red light.
