What is an advantage of using parallax rather than the Doppler effect to determine star distance?
Parallax is more accurate for stars that are very far away.
What determines galaxy motion and distance?
One of the most reliable methods employed presently is using Hubbles Laws and Constant, utilizing the red shift. RED SHIFT A+LS (:
How can scientists keep track of tornadoes?
Scientists track tornadoes using Doppler radar and reports from eyewitnesses.
What shift of color do you receive from stars as you get closer?
Blue shift as you get closer because by the Doppler effect, the frequency of the light increases, so the light seems more blue. Using the same logic, there is a red shift for light as you move away from stars.
How do people know when a star is moving toward or away from the earth?
blue shifted
How does a beluga whale determine whether a fish is moving away from it or toward it?
By using the Doppler effect
What is a Doppler rader and how is it used?
a radar tracking system using the Doppler effect to determine the location and velocity of a storm, clouds, precipitation, etc. Dop·pler ef·fectnoun Physicsnoun: Doppler effectan increase (or decrease) in the frequency of sound, light, or other waves as the source and observer move toward (or away from) each other. The effect causes the sudden change in pitch noticeable in a passing siren, as well as the redshift seen by astronomers.
What is an advantage of using parallax rather than the Doppler effect to determine star distance?
Parallax is more accurate for stars that are very far away.
What is the difference between a Doppler radar and a regular radar?
Normal radar sends out radio waves to determine the location of an object. Doppler radar can not only find the location of an object or storm, but using something known as the Doppler effect can determine how fast it is moving towards or away from the radar.
How can you measure the time using the stars?
light years
Complete the sentences by matching the phrases below?
Astronomers are able to determine the speed at which certain redshift stars move using: The doppler effect Radiotelescopes reveal that space is full of: Cosmic microwave background radiation Some astronomers study how matter behaves using: Particle accelerators The idea that everything in the universe came from a single dense ball 10 to 20 billion years ago has been named: The Big Bang Theory -Apex- :)
What would be a common task for astronomers?
using a telescope to determine the coordinates of a star
How does a speed camera calculate speed?
By using the "doppler" effect and measuring the change in frequency.
If Astronomers observe a typical star using a telescope and a spectrometer they will be able to determine what?
i have no idea but it uytr
How can you measure how fast the universe is expanding?
By using some method other than the Doppler effect to calculate the distance of a distant galaxy, and using the Doppler effect to see how fast it moves away from us. A galaxy's distance and how fast it moves away from us are roughly proportional.
How do astronomers create three dimensional maps of the universe?
by using the position on the sky and the redshift to determine a distance along the line of sight
How do astronomers create three-dimensional maps of the universe?
by using the position on the sky and the redshift to determine a distance along the line of sight
