Application +4 | -1

A certain material has refractive indices

1.56,1.60

and 1.68 for red, yellow and violet light respectively. (a) Calculate the dispersive power. (b) Find the angular dispersion produced by a thin prism of angle

6^{\circ}

made of this material.

View answer and explanation

Correct option: B

0.2;\,\,0.72^{\circ}

Option B (

0.2;\,\,0.72^{\circ}

) is correct because the dispersive power and angular dispersion are calculated using the given refractive indices and prism angle.
