Ray Optics
(Important Theory Questions)
1. Derive mirror formula for a concave mirror and convex mirror.
2. Derive an expression for lateral shift and normal shift. On what factors these depend.
3. Define TIR and write the conditions for TIR. Derive a relation between critical angle and the refractive index of the medium. Also explain the working of isosceles prism and optical fiber.
4. Derive the following relation for a real image formed by a convex refracting surface when the object is placed in rarer medium. Also write the assumptions and sign convention used.
μ₂ / v - μ₁/u = (μ₂ - μ₁) / R
