Due to Doppler's effect

Vedclass · Answer

(D) The correct answer is $D$. According to the Doppler effect,when a source of light moves away from an observer,the frequency of the emitted light decreases,which corresponds to an increase in wavelength. This shift towards longer wavelengths (the red end of the visible spectrum) is known as the red shift. Since light observed from distant galaxies consistently shows a red shift,it indicates that these galaxies are moving away from us. This observation provides strong evidence that the universe is expanding.
