WebThe lines are moved or shifted towards the red end of the spectrum. This effect is called red shift. The diagram shows part of the emission spectrum of light from a distant galaxy. Web21. okt 2024 · 9,248. james fairclear said: Yes, but the point I am making is that red shifted light is lower energy so that one would expect it to take longer for an equivalent amount of the emitted energy to be received at the destination. I think that wording is misleading because it is only true for a a certain interval of measuring a continuous power ...
WebRedshift and Hubble's Law. For very far objects (beyond about 1 billion light-years) none of the above methods work. Scientists must move from direct observation to using observations in conjunction with a theory. The theory … WebConversely, if the light was moving away from you, you'd again see the same pattern of light lines, but their frequencies would be shifted toward red. This is what's being measured when the spectra of stars and galaxies are measured: not just what the color looks like, but whether the spectra of things like hydrogen, helium and iron are shifted ...
