What can astronomers learn about the stars motion based on wavelength shifts?

They can determine how fast the star is moving toward or away from us. The chemical spectral signature is used to determine the Doppler shift of the visible light reaching us. This is then used to calculate how fast we and the star in question are moving toward or away from each other.

Is the telescope based on wavelength and frequency?
yes
Do astronomers use ground-based X-ray telescopes?
No they do not, or use gamma ray telescopes either. Not ground based.
What do astronomers use to look at planets?
Their eyes, ground-based telescopes, space telescopes.
Astronomers predicted the existence and orbit of Neptune based on?
neptune's gravitational effect on the orbit of uranus
What term do astronomers use for the time it takes for a planet to orbit the sun relative to the stars?
Astronomers use the term "sidereal period" to describe the time it takes for a planet to orbit the sun relative to the stars. Sidereal periods are measured based on the apparent motion of a planet against the background of fixed stars rather than against the sun. This allows for more precise measurements of a planet's orbital period.
Based on the observed red shifts in the spectral lines of distant galaxies?
Astronomers conclude that the universe is expanding, because wavelengths are increasing.
What are the implications of these shifts for international businesses based in HnogKong?
# What are the implications of the shifts for international businesses based in Great Britain, North America, and Hong Kong?
Is the telescope based on wavelength and frequency?
yes
What two regions of the electromagnetic spectrum are best utilized by ground based astronomers?
The two regions of the electromagnetic spectrum are best utilized by ground based astronomers are optical and radio.
What conclusion do astronomers make based on the red shift?
use your brain to answer it its ok for your answer.
What kind of shifts does a cop work?
The shifts vary based on manpower and the needs of the department. Most are eight or ten hour shifts, my last department was four - 12 hour shifts followed by four days off. Court appearances are often outside of regular duty hours.
Do astronomers use ground-based X-ray telescopes?
No they do not, or use gamma ray telescopes either. Not ground based.
Does frequency determine where a light wave appears on the electromagnetic spectrum?
Yes. c=fL where L = wavelength, c=speed of light and f = frequency (I cannot write the Greek letter lamda for wavelength)
What do astronomers use to look at planets?
Their eyes, ground-based telescopes, space telescopes.
What happen to the speed when frequency and wavelength change?
It would change, depending on how much the frequency and the wavelength changes. It varies based on v = fλ.
Astronomers predicted the existence and orbit of Neptune based on?
neptune's gravitational effect on the orbit of uranus
What is the color you see based on?
The frequency or wavelength of the light reflected from the object to your eye.
