Formula Sheet — Ray Optics and Optical Instruments

Important formulas and equations from Ray Optics and Optical Instruments for AIIMS Paramedical Physics.

Formulas — Ray Optics and Optical Instruments

Basic Laws and Reflection

∠i = ∠r
Number of images = 360°/θ - 1 (for even N) or N (for odd N)
R = 2f

Spherical Mirrors

1/v + 1/u = 1/f
m = -v/u = hi/ho
ml = -v²/u² = -(m)²
vi/M = -(v²/u²) × vo/M

Refraction and Snell's Law

μ₁ sin i = μ₂ sin r
μ = c/v
d = t sin(i-r)/cos r
Apparent depth = Real depth/μ

Total Internal Reflection

sin ic = μ₂/μ₁
ic = sin⁻¹(1/μ)
