I don't understand this. Could this be explained in an easy to understand way?
The light coming from stars is closer to
red (long wavelength, low frequency)
than we would expect. What does this
imply?
Your answer:
the universe is expanding
the universe is rotating
the universe is shrinking
the universe is static
Hello, here is the answer given by another expert. Seems to be different from your answer. . . Could you please double check the answer? Thank you so much. this answer is very important to me

- Two waves are travelling through outer space. Wave 1 has a frequency of 300 MHz and wave 2 has a frequency of 300 Hz. How does the speed of wave 1 (v1) compare to wave 2 (v2)? a) v1 = (1E-6)v2 b) v1 = (1E6)v2 c) v1 = 1/v2 d) v1 = v2arrow_forwardExplain why we see the Milky Way as a faint band of light stretching across the sky.arrow_forwardWhen a star or galaxy is moving away from us, we observe the Doppler effect by seeing the lines in its spectrum A. red-shifted (shifted toward the red end of the light spectrum) B. you can't fool me, the Doppler effect only applies to motions on Earth, not to the motions of the stars and galaxies O C. become darker and darker (like a blackbody) O D. yellow-shifted (shifted so all the colors become a little bit yellower) O E. blue-shifted (shifted toward the blue or violet end of the light spectrum)arrow_forward
- QUESTION 6 A galaxy is discovered at a distance of 11 billion light-years from our solar system. We can therefore say: O The galaxy was created within 3 million years after the Big Bang O We are currently observing the galaxy as it existed 11 billion years ago O The galaxy's light is observed at shorter wavelengths than nearby galaxies The galaxy has been 11 billion light-years from our solar system since the Big Bangarrow_forwardThe three most prominent spectral lines of hydrogen are H-α at 656 nm, H-β at 486 nm, and H-γ 434 nm. If we observe an object with H-α at a wavelength of 700 nm, what wavelength will we observe H-β and H-γ? Is the object moving toward or away from us, and how do you know? Suppose we observe another object with H-α at 585 nm. Is this object moving toward or away from us? Is it moving slower or faster than the first object?arrow_forwardYou record the spectrum of a distant star using a telescope on the ground on Earth. Upon analysing the spectrum, you discover absorption lines spaced at intervals typical of oxygen atoms. Which of the following are possible interpretations of this evidence? Select all that apply. The width of the spectral lines gives the diameter of the star The star is likely orbited by habitable planets with breathable atmospheres. The height of the spectral lines above the star's general blackbody spectral curve tells us how much oxygen is in the star The atmosphere of Earth contains oxygen The red or blueshift of the set of lines can tell us the speed of the star's motion toward or away from usarrow_forward
