Redshift and Universe

Front

What does redshift of light indicate about a star's movement?

Back

The star is moving away from Earth.

Front

What is the phenomenon called when galaxies move away from our galaxy and a shift on the electromagnetic spectrum is noticed?

Back

Redshift.

Front

What is one piece of evidence that supports the Big Bang Theory?

Back

Cosmic background radiation.

Front

What is cosmic background radiation?

Back

The remaining energy from the Big Bang.

Front

What type of wavelength does redshifted light have?

Back

Longer wavelength.

Front

What does blueshift of light indicate about a star's movement?

Back

The star is moving toward Earth.

Front

What is the electromagnetic spectrum?

Back

The range of all types of electromagnetic radiation.

Front

How does the Doppler effect relate to redshift and blueshift?

Back

It describes how the frequency of waves changes due to the motion of the source relative to the observer.

Front

What is the significance of cosmic background radiation in cosmology?

Back

It provides evidence for the early state of the universe after the Big Bang.

Front

What is the relationship between redshift and the expansion of the universe?

Back

Redshift indicates that galaxies are moving away from us, supporting the idea that the universe is expanding.
