Hint: See the comment following Equation $36.22$ .

Short Answer

Expert verified

$t^{1} = 纬 (t - \frac{v}{c^{2}} x)$

Step by step solution

Given Information

We have to derive the Lorentz transformations for $t$ and $t'$ .

Simplify

To derive the Lorentz transformations we have the below equation:

$纬 = \frac{1}{\sqrt{1 - \frac{v^{2}}{c^{2}}}} = \frac{1}{\sqrt{1 - 尾^{2}}}$

As we know that

$x = c t$ and

$x' = c t'$

Then,

$x' = 纬 (x - v y) x = 纬 (x' + v t) x x' = 纬^{2} (x x' + x v t' - v t x' - v^{2} t t' c^{2} t t' = 纬^{2} (c^{2} t t' + c t v t' - c t v t' - v^{2} t t') c^{2} = 纬^{2} (c^{2} - v^{2}) 纬^{2} = \frac{c^{2}}{c^{2} - v^{2}} 纬^{2} = \frac{1}{1 - \frac{v^{2}}{c^{2}}} 纬 = \frac{1}{\sqrt{1 - \frac{v^{2}}{c^{2}}}}$

Next,

$x = 纬 (x' - (- v) t') x = 纬 (x' + v t') \frac{x}{纬} = x' + v t' \frac{x}{纬} - x' = v t' \frac{x}{纬 v} - \frac{x'}{v} = t' t' = \frac{x}{纬 v} - \frac{纬 (x - v t)}{v} t' = 纬 (\frac{x}{纬^{2} v} - \frac{x}{v} + t) (E q . 1)$

To get a number for t, we need to simplify the indicated component of the equation and then return it to the same equation.

$\frac{x}{纬^{2} v} - \frac{x}{v} = x (\frac{1}{纬^{2 v}} - \frac{纬^{2}}{纬^{2} v}) \frac{1 - 纬^{2}}{纬^{2} v} = \frac{\frac{c^{2} - v^{2}}{c^{2} - v^{2}} - \frac{c^{2}}{c^{2} - v^{2}}}{\frac{c^{2} v}{c^{2} - v^{2}}} \frac{- v^{2}}{c^{2} - v^{2}} 路 \frac{c^{2} - v^{2}}{c^{2} v} = \frac{v}{c^{2}}$

To find the value for t, we'll now substitute values in equation (1).

$t' = 纬 (t - \frac{v}{c^{2}} x)$
