What is the Electromagnetic spectrum
Light Radiation organized by frequency and wavelength
200 Mystery Ball
What are the wavelengths of the Electromagnetic Spectrum
Radio, Microwave,Infrared, Visible,Ultraviolet,X-ray, Gamma Ray
300 Mystery Ball
Radio waves are very big and far apart (building size)Gamma waves are very small and close together (Atomic size)
The Waves at the Radio end of the spectrum are like?The waves at the Gamma end of the spectrum are like?
400 Mystery Ball
Visible &Infrared
What wavelength do we see in?What wavelength do we emit?
500 Mystery Ball
Describes the relationship between the wavelength of maximum intensity and the temperature. (Hot - Blue) (Cold - Red)
Wein's Law states what?
100 Mystery BallSpiral,Elliptical, irregular
What are the three basic types of Galaxies?
200 Mystery BallBarred spiral and the Milky way
What type of Galaxy do we live in and what is it called?
300 Mystery Ball
Infrared, visible, x-ray, radio
What are the common wavelengths to view a galaxy?
400 Mystery BallElliptical galaxies have almost no dust or gas between the stars
What is one major difference between a spiral and an Elliptical galaxy?
500 Mystery BallThe farther away the galaxy is the faster it will move away from you.
According to Hubble's law Galaxies move how in relation to us?
100 Mystery Ball
Color, Temperature, Size, Chemical, Composition, and Brightness
What are the ways to classify stars?
Mystery Ball200 Blue
In accordance to Wein's law the hotter younger stars are ______in color.
Mystery Ball300 Earth, 20km
White dwarf stars can be as small as _____ and Neutron stars can be as small as _______
Mystery Ball400ApparentAbsolute
_______ is the brightness as seen by the Eye.______ is the brightness after adjusting for the
distance of the star
Mystery Ball500
Surface temperature and Absolute brightness
The Hertzsprun-Russell diagram uses the graphing of these two qualities to see the pattern of star types.
Mystery Ball100 Spectroscope
We use this to analyze visible wavelenths
Mystery Ball200
Refracting and Reflecting
What are the two type of optical telescopes?
Mystery Ball300
Atmosphere - place telescope on high mountains, or in spaceLight pollution - place far away from civilization or in spaceWavelength interference - in a valley
What interferes with telescopes and what do we do to avoid the
problems?
Mystery Ball400Make brighten objects of the same color range and darken objects of opposite color range
Color filters can do this to objects
Mystery Ball500Different elements that are in that star.
Spectroscopy can be used to see what in different stars?
A light-year is?
Mystery Ball100
The distance that light travels in one year, about 9.46 trillion km
Mystery Ball200Scientific Notation
Scientists us this notation because the distances between objects in space are so large
Mystery Ball300
Because the stars are so far away the light we see left that star system millions of years ago.
The light from the stars is like looking into the past why?
Mystery Ball400 12
Solve the following equation!3x + 2 =38
Mystery Ball500
Big/far awaySmall/very close
In scientific notation a positive exponent means the object is ______ and a negative exponent means an
object is _______.
According to the Big Bang theory this is how the universe began.

Final Question
The theory asserts that our entire universe was created when a tiny (billions of times smaller than a proton), super-dense, super-hot mass "exploded" and began expanding very rapidly, eventually cooling and forming into the stars and galaxies with which we are familiar.
