1 Medium

1 of 1

Application +4 | -1

For a material medium, the values of refractive index for violet and red colours are given as

\mathrm{n}_{\mathrm{v}}=1.56

and

\mathrm{n}_{\mathrm{r}}=1.44

. The dispersive power of a prism made out of this material is

View answer and explanation

Correct option: B

0.24

Option B (0.24) is correct because the dispersive power is calculated using the refractive indices for violet and red colors.
