Hubble showed that the universe as a whole is expanding and the distant stars are receding from us. The spectral line from a star, when compared with the corresponding line from an source will then show
A
A shift in frequency towards the red end
B
A shift in frequency towards the violet end
C
No shift in frequency at all
D
A shift in frequency towards the violet end as well as a decrease in intensity
Answer
A shift in frequency towards the red end
Explanation
Solution
When distant stars are receding from us, spectral line from the star, when compared to with the corresponding line from source will show red shift i.e. a shift in frequency towards the red end.
