WebRefractive index, μ = 2 Step 2: Determine the value of r The condition for minimum deviation is, r = A 2 (where r is the angle of reflection and i is the angle of incidence) ⇒ r = 60 2 = 30 ° Step 3: Determine the value of i Using the formula for the refractive index of … WebNo phase change takes place when reflecting from a medium of lower refractive index (Figure 3.13). Because of the periodic nature of waves, this phase change or inversion is equivalent to ± λ / 2 ± λ / 2 in distance travelled, or path length. Both the path length and refractive indices are important factors in thin-film interference.
