Astronomical wavelength increase due todoppler effect known as
Options
- ARed shift
- BVoilet shift
- CUV
- DIR shift
Correct answer
A. Red shift
Step-by-step solution
In physics (namely astrophysics), redshift happens when light or other electromagnetic radiation from an object moving away from the observer is increased in wavelength or shifted to the red end of the spectrum.
