Question

In the experiment to find the refractive index of an equilateral prism , the value of
angle of deviation (d) and the angle of incidence are given in the following table?
1 20 25
35 40 45 50
d
37 35 32 30 32 36 39
from the above information, answer the following.
1) Find the angle of minimum deviation
ii) At the angle of minimum deviation, what will be the angle of emergence ? Why?
1) Which property of light make it disspressed through prism with different deviation
angles ?
iv) What will be the refraction index of the prism used in above experiment.​
