In the experiment to find the minimum deviation for a glass prism, by ray tracing, the deviation (δ) is measured for different values of the angle of incidence (i). Which of the following plots of δ against i is closest to the experimental result?
Correct Answer is: (b)
Sharp images are obtained for small angles of incidence. For large angles of incidence, the images become indistinct and proper ray tracing becomes difficult.
