Time Dilation and Length Contraction

This section is part of the HSC Physic syllabus Module 7: Nature of Light under Light and Special Relativity.

In this post, we will investigate the evidence, from Einstein’s thought experiments and subsequent experimental validation for the following:

  • Time dilation
  • Length contraction

 

Time dilation

The formulae for time dialation is the following:

t = \frac{t_0}{\sqrt{\frac{1-v^2}{c^2}}} 

 

Length contraction

The formula for length contraction is the following:

L = L_o \sqrt(1-\frac{v^2}{c^2})
