Red Shift Flashcards
When something is moving away from you the frequency seems …
Lower
Does the Doppler effect work in both types of wave
Yes
Different elements absorb….
Different frequencies of light
The frequency that a element absorbs creates a
pattern on the element
What is different about the patterns made on elements on different planets
They are shifted to the red side of the spectrum
What does red shift show
That distant planets are moving away
When did the Big Bang happen
14 billion years ago
Name and describe an alternate theory to the creation of universe
Solid state- that the universe is the same as it always has been and red shift is just new matter being created
Other than red shift what else provides evidence for the Big Bang theory
Cosmic microwave background radiation (CMBR)
Why does CMBR help explain the Big Bang theory
Because wen the Big Bang occurred lots of hot energy was formed this has slowly cooled leaving microwaves
Name two limitations to the Big Bang Theory
Unexplainable observations (theory predicts the universe to be shrinking but is expanding) It can't explain what was there in the first place
When an object moves towards you the frequency seems…
