Derive the Lorentz transformations for time from the transformations for space.
Inverse Lorentz from formation
x = γ(x' + vt'), r = 1/√1 – v2/c2
and
x' = γ(x – vt)
⇒ x = γ(γx – γvt + γt')
x(1 – γ2) = - γ2vt + γvt'
1 – γ2 = 1 – 1/1 – v2/c2 = -v2/c2/(1 – v2/c2) = - γ2v2/c2
- γ2v2/c2 x + γ2vt = γvt1
t1 = γ(t – vx/c2), For v/c → 0, γ → 1
⇒ t1 = t
⇒ t1 = t
