Question

Assuming that universe is expanding, if the spectrum of light coming from a star which is going away from earth is tested, then in the wavelength of light(a) There will be no change(b) The spectrum will move to infrared region(c) The spectrum will seems to shift to ultraviolet side(d) None of the above

Answer 1

The correct answer is:

(b) The spectrum will move to infrared region

Explaination:

Due to expansion of universe the star will go away from the earth thereby increasing the observed wavelength.

Therefore, the spectrum will shift to an infraded region.
