1What does CMBR stand for?
- ACosmic microwave background radiation
- BCosmological microwave background radiation
- CCosmic microwave background radiography
2What are the three main pieces of evidence for the Big Bang Theory?
- AWe can still hear the explosion with special equipment
- BWe can detect radiation left over from the big bang (CMBR)
- CWe can tell that all distant galaxies are moving away from us because they are red-shifted
- DWe can tell that all distant galaxies are moving closer to us because they are red-shifted
- EVery distant galaxies move faster away from us than closer ones
3The light from distant galaxies appears more blue than it should because the waves emitted have a shorter wavelength due to the doppler effect
- AVerdadero
- BFalso
4How old is the universe estimated to be?
- A13.7 thousand years old
- B13.7 million years old
- C13.7 billion years old
5The further away a galaxy is from us, the faster it is moving away from us
- AVerdadero
- BFalso
6According to the Doppler effect, what happens to sound waves emitted at a constant pitch from a car moving towards you?
- AThey move more quickly, so their pitch increases
- BTheir wavelength increases, so their pitch increases
- CTheir frequency increases, so their pitch increases
7What piece of evidence is only explained using the Big Bang Theory?
- ACMBR
- BRed shift
8What do missing wavelengths/black lines on the spectrum of light wavelengths emitted from a star mean?
- AThese are the chemical components of dust in space between us and the star absorbing certain light frequencies
- BThese are the chemical components of the star absorbing certain light frequencies
- CThese form when there are solar flares which interrupt the emission of light from the star
9All elements absorb the same wavelength of light
- AVerdadero
- BFalso
10The absorption lines on the Spectra of distant galaxies are shifted ______ relative to the sun
- ARed
- BBlue
