Redshift means stars and galaxies are emitting a color that is shifting toward the red end of the color spectrum. this indicates the light's wavelengths are and less frequent, and the star or galaxy

Redshift means stars and galaxies are emitting a color that is shifting toward the red end of the color spectrum. this indicates the light's wavelengths are MORE and less frequent, and the star or galaxy is MOVING AWAY

Explanation:

As we know that by Doppeler's effect of light when source is moving away from the observer then the frequency observed by the observer is given as

so here on moving away the frequency observed by observer will decrease and hence we can say that the wavelength of light must be increased

So here on increasing the observed wavelength we say it to be shifted towards higher side which means it is red shift

so here correct answer would be

Redshift means stars and galaxies are emitting a color that is shifting toward the red end of the color spectrum. this indicates the light's wavelengths are MORE and less frequent, and the star or galaxy is MOVING AWAY
