Length contraction is a phenomenon where an object appears shorter in the direction of its motion compared to its length in the direction perpendicular to its motion. This is a consequence of the time dilation effect, which is the apparent slowing down of time passing for an observer moving relative to a moving object.
Time dilation is the apparent slowing down of time passing for an observer moving relative to a moving object. This is a consequence of the fact that the observer is moving through a region of spacetime where time is dilated.
Examples:
A clock moving at high speed will appear to run slower than a clock at rest.
A light beam traveling through a moving medium will be bent towards the direction of motion.
A rod placed lengthwise in a moving train will appear shorter than when it is placed perpendicular to the direction of motion.
These effects are commonly observed in various experiments and observations in special and general relativity.
