Galileo
Copernicus
Kepler
Brahe
8
Which is NOT a type of electromagnetic radiation found on the electromagnetic spectrum?

9
Roughly, the time required for the Earth to orbit once around the sun..
month
week
year
day
10
Which of the following indicates the universe was expanding?
observations of redshift
the discovery of other galaxies
an increase in the # of constellations in the sky
a growing celestial sphere
11
Where do scientists put telescopes to avoid interference from Earth's atmosphere?
in valleys
in cities
in space
in deserts
12
What is an advantage of a reflecting telescope?
It can focus images perfectly
It can use very small lenses
It can gather more light.
It can detect distant objects
13
He created the sun-centered (heliocentric) theory of the universe.
Copernicus
Galileo
Ptolemy
Brahe
14
What does a telescope collect from space & focus for closer observation?
electromagnetic radiation
magnetic particles
lenses
wavelengths
15
The angle between an object in the sky & the horizon.
constellation
horizon
astrolabe
altitude
16
The line where the sky and the Earth appear to meet.
constellation
astrolabe
horizon
altitude
17
A region in the sky that contains a recognizable star pattern.
altitude
astrolabe
horizon
constellation
18
He created an Earth-centered (geocentric) theory of the universe..
Copernicus
Ptolemy
Brahe
Newton
19
How does Earth's atmosphere affect starlight?
It causes it to change colors.
It causes it to shimmer & blur.
It stretches it.
It blocks it.
20
What makes up the electromagnetic spectrum?
all of the wavelengths of electromagnetic radiation
all colors of visible light
microwaves, gamma rays, & x-rays
all colors of invisible light
21
He proved that there were many galaxies.
Brahe
Ptolemy
Hubble
Copernicus
22
What is the imaginary sphere, created by scientists, that surrounds the earth?
an astrolabe
a celestial sphere
a zenith
an ecliptic
23
What does the Earth's atmosphere do to most types of electromagnetic radiation?
blocks them
stretches them
freezes them
absorbs them
24
Roughly, the time required for the Earth to rotate once on its' axis.
week
month
day
year
25
Which of these would be shorter if Earth rotated faster?
weeks
months
years
days
26
An advantage of reflecting telescopes over refracting telescopes is that
mirrors only reflect certain colors of light for focus
they use lenses to focus light
mirror sizes are all the same for ease of use
flaws in the glass don't affect the incoming light
27
An instrument that uses a set of lenses to focus light.
horizon
altitude
astrolabe
telescope
