to find angle of deviation with angle of incidence through a hollow prism with different transparent fluids(i.e ., water,kerosene,sprit,turpentine oil) with angle of incidenceof30,35,40,45,50,55,60 degree.

• physics -

Angles of incidence and refraction are angles measured from the normal.

If n represents the refractive index between air and the medium, the equation that governs the relationship between them is

n=sin(θi)/sin(θr)
which gives the value of θr as
θr=sin-1(sin(θi)/n)

Since n>1 for the media named in the question, the refracted ray would bend towards normal.

Example calculation:
Take n=1.33 for water.
Angle of incidence, θi=30°
Angle of refraction
θr=sin-1(sin(θi)/n)
=sin-1(sin(30)/1.33)
=sin-1(.3836)
=22.56°
Deviation
= 30-22.56°
=7.44°

Review your class notes and/or textbook if it is still not clear.
