Mystery Ball100

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.
