Optics Calculator

Analyze light behavior through lenses, mirrors, and refraction using fundamental optics principles. Calculate image formation, magnification, and light bending with support for both SI and imperial units along with visual ray diagrams.

Formulas Used

  • Lens/Mirror Formula: 1/f = 1/dₒ + 1/dᵢ
  • Magnification: m = -dᵢ / dₒ
  • Image Height: hᵢ = m × hₒ
  • Snell’s Law: n₁ sin(θ₁) = n₂ sin(θ₂)
  • Critical Angle: θc = sin⁻¹(n₂ / n₁)

Use Cases

  • - Image formation in lenses and mirrors
  • - Camera and optical device design
  • - Fiber optics and light transmission analysis
  • - Physics assignments and ray diagram problems
  • - Engineering optics and vision systems
