Derive the formula for angle of deviation for thin prisms.
For thin prisms (refracting angle < sin 10°). sin θ ≈ θ ∴ Refractive index, n = \(\frac{sin\,i}{sin\,r_i}\) ≈ \(\frac{i}{r_1}\) Also n = \(\frac{sin\,e}{sin\,r_2}\) ≈ \(\frac{e}{r_2}\) ∴ i ≈ n r1 and e ≈ nr2 ii. Substituting this in, i + e =...
