Explore how the Doppler effect works in space and its crucial role in space exploration.
The Doppler effect in space is a phenomenon where the frequency of electromagnetic waves (like light or radio waves) changes based on the relative motion between the source and the observer.
In space, this effect is crucial for:
When a source moves away from an observer, the waves are stretched, causing a redshift. Conversely, when a source moves towards an observer, the waves are compressed, causing a blueshift.
