Time Dilation
Time dilation refers to the phenomenon where the passage of time appears to be slower for objects moving at high speeds compared to those at rest. This apparent slowing down of time is a result of the length contraction of time, which is the apparent reduction in the length of an object moving at high speed.
Length Contraction
According to the theory of special relativity, the length of an object moving at high speed is shorter than its length at rest. This phenomenon is known as length contraction. The length contraction is just one of the many fascinating consequences of special relativity, which includes the famous time dilation experiment.
Examples
An observer traveling at 99% of the speed of light will experience time dilation.
A moving clock will appear to run slower than a clock at rest.
When a light ray is emitted from an object moving at high speed, the light will be bent towards the observer's direction.
Key Points
Time dilation is a real phenomenon, not an observer's perception.
It is a consequence of the length contraction of time.
Time dilation is only relevant for objects moving at high speeds.
The length contraction is a very small effect, but it has been verified experimentally
