Zusammenfassung der Ressource

Frage 1

Frage
What does CMBR stand for?
Antworten
  • Cosmic microwave background radiation
  • Cosmological microwave background radiation
  • Cosmic microwave background radiography

Frage 2

Frage
What are the three main pieces of evidence for the Big Bang Theory?
Antworten
  • We can still hear the explosion with special equipment
  • We can detect radiation left over from the big bang (CMBR)
  • We can tell that all distant galaxies are moving away from us because they are red-shifted
  • We can tell that all distant galaxies are moving closer to us because they are red-shifted
  • Very distant galaxies move faster away from us than closer ones

Frage 3

Frage
The light from distant galaxies appears more blue than it should because the waves emitted have a shorter wavelength due to the doppler effect
Antworten
  • True
  • False

Frage 4

Frage
How old is the universe estimated to be?
Antworten
  • 13.7 thousand years old
  • 13.7 million years old
  • 13.7 billion years old

Frage 5

Frage
The further away a galaxy is from us, the faster it is moving away from us
Antworten
  • True
  • False

Frage 6

Frage
According to the Doppler effect, what happens to sound waves emitted at a constant pitch from a car moving towards you?
Antworten
  • They move more quickly, so their pitch increases
  • Their wavelength increases, so their pitch increases
  • Their frequency increases, so their pitch increases

Frage 7

Frage
What piece of evidence is only explained using the Big Bang Theory?
Antworten
  • CMBR
  • Red shift

Frage 8

Frage
What do missing wavelengths/black lines on the spectrum of light wavelengths emitted from a star mean?
Antworten
  • These are the chemical components of dust in space between us and the star absorbing certain light frequencies
  • These are the chemical components of the star absorbing certain light frequencies
  • These form when there are solar flares which interrupt the emission of light from the star

Frage 9

Frage
All elements absorb the same wavelength of light
Antworten
  • True
  • False

Frage 10

Frage
The absorption lines on the Spectra of distant galaxies are shifted ______ relative to the sun
Antworten
  • Red
  • Blue
