When the sun rotates, one end of the equator moves towards us & the other moves away from us.
So, the difference given is basically the difference between the red & blue shift
Now, using the non relativisitic doppler effect (since the speed of sun is much less than C)
v = 2.2 km/s
The correct answer is: 2.2
The correct answer is: 2.2

The Lyman is a term that can refer to several different things:
1. Lyman Series: In physics, the Lyman series refers to a set of spectral lines in the ultraviolet region of the electromagnetic spectrum. These lines are emitted when electrons in hydrogen atoms transition from higher energy levels to the lowest energy level (n=1). The Lyman series is named after its discoverer Theodore Lyman.
2. The Lyman Alpha Forest: In cosmology, the Lyman alpha forest is a series of absorption lines seen in the spectra of distant quasars. These absorption lines are caused by intervening clouds of neutral hydrogen gas along the line of sight between the quasar and the observer. The Lyman alpha forest provides valuable information about the distribution of matter in the early universe.
3. The Lyman Break Technique: In astronomy, the Lyman break technique is a method used to identify distant galaxies. It relies on the fact that the Lyman alpha emission line from hydrogen gas in these galaxies is shifted to longer wavelengths (redshifted) due to the expansion of the universe. By looking for a drop in flux at the Lyman alpha wavelength, astronomers can identify galaxies that are billions of light-years away.
4. Lyman Spitzer Jr.: Lyman Spitzer Jr. was an American theoretical physicist, astronomer, and mountaineer. He is often referred to as the "Father of the Space Telescope" for his advocacy and leadership in the development of the Hubble Space Telescope. His work laid the foundation for the field of space astronomy.
