8. The accompanying diagram shows the path that a light ray takes passing through three transparent materials. The indices of refraction in materials 1,2 , and 3 are

\mathrm{n}_{1}, \mathrm{n}_{2}

, and

\mathrm{n}_{3}

, respectively. Which of the following best describes the relation between the indices of refraction? (A)

\mathrm{n}_{1}>\mathrm{n}_{2}>\mathrm{n}_{3}

(B)

\mathrm{n}_{1}>\mathrm{n}_{3}>\mathrm{n}_{2}

(C)

\mathrm{n}_{2}>\mathrm{n}_{1}>\mathrm{n}_{3}

(D)

\mathrm{n}_{3}>\mathrm{n}_{1}>\mathrm{n}_{2}
