Aim/Objectives:
The aim of this project is to investigate dependence of angle
of deviation on angle of incidence using a hollow prism filled
one by one with different transparent fluids.
Hypothesis:
Apparatus Required:
2. Liquids like-
3. Bell pins
Theory:
U= =
Where-
U=refractive index of the liquid.
a = angle of minimum deviation
d=angle of prism
i=angle of incidence
r=angle of refraction
Diagrams:
Process:
Remove the prism and draw the line joining the points
so obtained.
Observations:
Benzaldehyde:

Conclusion:
The refractive indices change when the liquid used in the
prism changes. From the above experiment we can also
