Which statements accurately describe the Doppler effect? Check all that apply. It is used to learn about the behavior of the universe. It was used by Hubble to measure velocities of galaxies. It indicates galaxy motion through light wavelengths. It indicates a galaxy moving toward Earth through red shift. It indicates a galaxy moving away from Earth through blue shift.
Answers
The following were the options which were to be analysed:
1- It is used to learn about the behavior of the universe.
2-It was used by Hubble to measure velocities of galaxies
3- It indicates galaxy motion through light wavelengths.
4- It indicates a galaxy moving toward Earth through red shift.
5- It indicates a galaxy moving away from Earth through blue shift.
What is the Doppler effect?
The Doppler effect is the change in frequency or wavelength of a wave in relation to observer who is moving relative to the wave source.
The total Doppler effect may therefore result from motion of the source, motion of the observer, or motion of the medium.
The approaching and receding speed of galaxies and stars are calculated by the Doppler Effect. The Doppler Effect can also be defined as the observed change in frequency when there is a relative motion between the source of the frequency and the observer.
Doppler Effect can be implemented to measure the approaching and receding of sound and light.
Hence the correct answers for your question are options (A, B, and C)
- It is used to learn about the behavior of the universe.
- It was used by Hubble to measure velocities of galaxies
- It indicates galaxy motion through light wavelengths.
