The refractive indices of crown prism for violet and red lights are $1.523$ and $1.513$ . Dispersive power of prism is
$0.19$
$0.019$
$0.0019$
$19$

Dispersive power, $w = \frac{μ_{v} - μ_{r}}{μ_{y} - 1}$

where, $μ_{y} = \frac{(μ_{v} + μ_{r})}{2}$

So, $μ_{y} = (1.523 + 1.513) / 2 = 1.518$

Therefore $w = \frac{1.523 - 1.513}{1.518 - 1}$

$= 0.019$

The refractive indices of crown prism for violet and red lights are 1.523 and 1.513. Dispersive power of prism is0.190.0190.001919

Dispersive power, w=μv−μrμy−1 where, μy=(μv+μr)2So, μy=(1.523+1.513)/2=1.518Therefore w=1.523−1.5131.518−1 =0.019
