Homework Statement
This problem deals with the displacement of a light ray as it travels through a glass medium.
Starting with the equation #1: d=S[sin(i)cos(r)-cos(i)sin(r)]
(where d=the length of displacement of the light ray in the glass medium, i=angle of incidence, r=angle of refraction in the glass medium, S=the length of the light ray in the glass medium)
equation #2: d=tsin(i)[1-(cos(i)/(n^2-sin^2(i))^1/2)]
(where t=the glass thickness, n=the index of refraction of the glass)
-Derive equation #2 from equation #1
Homework Equations
Snell's Law: (n1)(sin(angle1)) = (n2)(sin(angle2))
n=1 for the air medium outside the glassk,k,k,
d=(S)[sin(i-r)]=equation #2
(S)[cos(r)]=t
