Define angle of deviation. Show that angle of deviation incase of refracion of light through a prism is `delta = i_1+i_2 -A` where the symbols have their usual meanings.

Prove that barx_1 < barx < barx_2 where the symbols have their usual meanings.

Deduce the equation s = ut +(1)/(2) at^(2) , where symbols have their usual meanings.

The angle of deviation of a ray of light refracted through a parallel glass slab is

Under what condition the angle of deviation of a refracted ray through a prism will be minimum? '

For minimum deviation delta_(m) , assuming that angle of incidence = angle of emergent, show that the refractive index of the material of the prism is mu = (sin""(A + delta_(m))/(2))/(sin""(A)/(2)) Or, Show the ray diagram of a ray of light through a thick another face. Show that delta = i _1 + i_2 - A and A = r_1 + r_2 . The symbols have their usual meaning.

What do you mean by angle of deviation of a ray in case of refraction through a prism. Calculate the expression of the angle of deviation.
