Question 1
Question
What does CMBR stand for?
Answer
-
Cosmic microwave background radiation
-
Cosmological microwave background radiation
-
Cosmic microwave background radiography
Question 2
Question
What are the three main pieces of evidence for the Big Bang Theory?
Answer
-
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
Question 3
Question
The light from distant galaxies appears more blue than it should because the waves emitted have a shorter wavelength due to the doppler effect
Answer
- True
- False
Question 4
Question
How old is the universe estimated to be?
Answer
-
13.7 thousand years old
-
13.7 million years old
-
13.7 billion years old
Question 5
Question
The further away a galaxy is from us, the faster it is moving away from us
Answer
- True
- False
Question 6
Question
According to the Doppler effect, what happens to sound waves emitted at a constant pitch from a car moving towards you?
Answer
-
They move more quickly, so their pitch increases
-
Their wavelength increases, so their pitch increases
-
Their frequency increases, so their pitch increases
Question 7
Question
What piece of evidence is only explained using the Big Bang Theory?
Answer
-
CMBR
-
Red shift
Question 8
Question
What do missing wavelengths/black lines on the spectrum of light wavelengths emitted from a star mean?
Answer
-
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
Question 9
Question
All elements absorb the same wavelength of light
Answer
- True
- False
Question 10
Question
The absorption lines on the Spectra of distant galaxies are shifted ______ relative to the sun
Answer
-
Red
-
Blue
