In the context of electromagnetic waves, what is a shift toward a higher frequency called?
Answer
Blueshift
A shift toward a higher frequency, corresponding to shorter wavelengths, is known as a blueshift, which indicates that the source of the electromagnetic waves is moving closer to the observer.
