Example 3-h Using the refracting and the deviation equations (3-1, 3-2, 3-3, and 3-5), derive the relationships for normal incidence. Substituting Q\ = 0° into the equations, one can easily derive the relationships described: (3-1) ns sin θ! = n sin θ\ n sin0° sinB'^-^ n P 0 ΘΊ = 0ο e'^shT^O ) (3-2) γ = θ , 1 +θ 2 = 0 ο +θ 2 Υ = θ2 (3-5) δ = θλ + θτ2 - γ = 0°+θ' 2 - γ or θ'2 = δ + γ δ = θ'2 - γ sinG'^O 0 52 The Geometrical Optics Workbook Example 3-i Light is incident on the front refracting surface of a prism such that the refracted angle is 25° and the emergent ray leaves normal to the back refracting surface.

Concepts (2-3) Law of Reflection Figure 2-6. Example 2-e. The left diagram in Figure 2-6 shows the incident ray striking the interface at an angle of 20° from the normal. According to the Law of Reflection, the reflected ray (QT{) will leave this interface at 20° from the normal. Looking at the diagram on the right, the normal to the surface may be represented by β+ θΓΐ=90° or ß = 90°-20° = 70° The sum of the internal angles of a triangle are equal to 180° (ß + a + 90° = 180°). Substituting for ß and solving for a: a =180°-90°-70° = 20° Because the normal to the second surface is 90°, the incident angle at the second surface is equal to θ2 = 90°- α = 90°- 20° = 70° Using the Law of Reflection, the final reflected angle (6r2) is equal to 70°.

Law of Reflection Light that is reflected at an interface leaves the surface traveling in the opposite direction (Figure 2-5). For any incident angle, the angle of reflection may be calculated using the Law of Reflection: The angle of incidence is equal to the angle of reflection. normal incident angle Incident ray intprfapp V reflected angle 0i medium 1 n medium 2 n* reflected ray ^^ Figure 2-5.
