The time period of rotation of the sun is 25 days and its radius is

7 \times {10^8}\;m

. The Doppler shift for the light of wavelength

6000\mathop \mathrm{A}\limits^ \circ

emitted from the surface of the sun will be

View answer and explanation

Correct option: A

0.04\mathop \mathrm{A}\limits^ \circ

Option A (

0.04\mathop \mathrm{A}\limits^ \circ

) is correct because it is calculated using the Doppler shift formula and the sun's rotational velocity.
