Expert Solution
Concept and Principle:
  • Time is not absolute. Time will slow down as we get closer to the speed of light. As per the special theory of relativity time measured by a clock that is moving will be slower than the time measured by a clock that is at rest.

 

  • The actual time or proper time is defined as the time that is measured in the clock's rest frame.

 

  • Time dilation is calculated using the following formula,

Δt=Δt01v2c2

Here ∆t is the dilated time, ∆t0 is the proper time, v is the velocity, and c is the speed of light.
