REFRACTING INDEX OF PRISMUSING SNELLS LAW AND ANGLE OF PRISM FORMULA
AIM
Using pins with a given prism determine the angles of deviation for different values of angle of incidence. Draw the graph of angle of deviation versus angle of incidence. Determine, from this the angle of minimum deviation and determine refractive index of material of the prism.
DISPERSION OF LIGHT IN PRISM
MOTIVATION BEHIND THE EXPERIMENT
Scientist wanted to quantify the factor by which light deviated
Physical measurable quantities are angle of incidence, angle of refraction and angle of prism
Scientist derived a simple formula relating the unknown factor with measurable quantities

CALULATION
Calculating the values of angle of incidence and emergence we get the angle of deviation D= I + E – A
Using the minimum deviation formula we can calculate the refractive index of the prism
