Speed of light, c = 3 × 108 m/s. Lorentz Transformations: x = γ (x − vt) x = γ (x + vt ) γ= Relative Velocity: u= Law of Addition of Velocities: u=
u +v v 1+ u 2 c u−v 1− uv c2 t = γ (t − vx ) c2 t = γ (t + vx ) c2
1 1− v2 c
2 Doppler eﬀect (for light from a receding source): f = f0
1− v c 1+ v c Instructions
