Question

Conclusion for finding the refractive index of prism

Answer 1

Answer:

this is the conclusion

.................

Answer 2

conclusion : by using three lasers of different wavelengths to get an accurate measurement for the apical angle of a prism, and then getting the minimum angle of deviation for these wavelengths, the unknown refractive index of the prism can be evaluated to a moderately high level of accuracy.

Hope this helps you !!
