⚡ Speed of Light Calculator
Calculate light speed in different media and relativistic effects
📐 Speed of Light Formulas
c = c₀ / n
c = λ × f
E = mc²
c = speed in medium, c₀ = vacuum speed, n = refractive index, λ = wavelength, f = frequency

💡 Tips & Information
- Speed of light in vacuum: 299,792,458 m/s
- Light slows down in denser media
- Wavelength and frequency are inversely related
- E = mc² relates mass and energy
- Refractive index affects light speed and bending
