Blue shift is light coming towards the observer.
What is blue shift?
100
As an ambulance comes towards you the pitch get higher.
What is an example of the Doppler effect?
100
The theory that all matter and energy in the universe was compressed into an extremely small volume that 13 billion to 15 billion years ago exploded and began expanding in all directions.
What is big bang theory?
100
A tool used for breaking down light waves.
What is a spectroscope?
100
a band of colors, as seen in a rainbow, produced by separation of the components of light by their different degrees of refraction according to wavelength.
What is a spectrum?
200
Red shift is light moving away from the observer.
What is red shift?
200
an increase (or decrease) in the frequency of sound, light, or other waves as the source and observer move toward (or away from) each other. The effect causes the sudden change in pitch noticeable in a passing siren, as well as the redshift seen by astronomers.
Define Doppler effect
200
When the universe was being formed, there was a giant explosion.
How did the Big Bang theory get it's name?
200
shorter
Does red have a shorter or longer wavelength?
200

what is the tilt of earth

23.5

300
The band of colors produced when white light passes through a prism.
Define spectrum.
300
Doppler effect happens because there is relative motion between a wave source and an observer.
Why does the Doppler effect happen?
300
about 13.7 billion years ago
How long a go did the Big Bang happen?
300
longer
Does blue have a shorter or longer wavelength?
300

what telescope helped discover far off galaxies

hubble

400
The study of the origin, properties, processes, and evolution of the universe.
What is cosmology?
400
yes.
Does the Doppler effect occur in light waves.
400
Hubble's Law Red shift Background radiation
Name the three theories that relate to the Big Bang theory.
400
Around 500 nanometers
Where does red fall in the spectrum?
400

A 100-gram sample of an isotope has a half-life of 3 days. How much substance remains after 12 days?

6.25g

500
A law of cosmology stating that the rate at which astronomical objects in the universe move apart from each other is proportional to their distance from each other.
What is Hubble's Law?
500
Redshift
When a light is moving away from the observer, what is this called?
500
Explosion, Expansion, Stars, Planets, Galaxies
List the sequence of the Big Bang theory?
500
Hydrogen, Mercury, Helium
What 3 gases did we test?
