kékeltolódás
Kékeltolódás, also known as blueshift, is a phenomenon in astronomy and physics where electromagnetic radiation from an object undergoes an increase in frequency and a decrease in wavelength. This occurs when the source of the radiation is moving towards the observer. In simpler terms, the light waves are compressed, shifting them towards the blue end of the visible spectrum.
The opposite effect is called redshift, where radiation from an object moving away from the observer experiences
Astronomers use kékeltolódás to determine the radial velocity of celestial objects. By measuring the precise shift
While kékeltolódás is most commonly discussed in the context of visible light, it applies to all forms
