A lens, a mirror, paper tube.
Cardboard, mirror, scissors, tape
CD, cardboard, scissors and tape
A metal wire, a battery and cardboard
2
What are the advantages of using a telescope compared with the naked eye?
Images are magnified and we can see fainter objects
It can record data
It looks cooler
It is more expensive
3
The pictures shows a method to find the focal length. The focal length is thenmeasured as…
the distance from the lens to the screen
the distance from the lens to the object
the diameter of the lens
the thickness of the lens at its thickest point
4
Which astronomer suggested the heliocentric model of the solar system?
Copernicus
Newton
Galileo
Ptolemy
5

396,000s
3.63s
3.64s
0.275 s
6
When a ray of light passesfrom air into water, it changes direction because…
light travels faster in water than in air
light travels slower in water than in air
light is reflected by the water molecules
the speed does not change
7
Astronomers use both earth and space telescopes. Which is an advantage of Earth telescopes?
The atmosphere makes the image clearer
They are easier to maintain
They can be used during the day and night
They can see all parts of the sky
8
In the reflecting telescope shown above, there will be a curved primary mirror and…
only one other mirror
nothing else is needed
at least one more mirror and one lens
only one other lens
9
In a reflecting telescope, the purpose of the primary mirror is to…
magnify an image produced by the eyepiece lens
absorb as much light as possible
support the body of the telescope
gather light and focus an image of the distant object
10

11
If the wave speed is 1000 m/s, and the frequency is 400 Hz, what is the wavelength?
2.5 m
25 m
400,000 m
0.4 m
12
Refracting telescope: the objective lens makes an image of a distantobject. The eyepiece lens-
magnifies this image
distorts this image
reduces the size of this image
dimisnishes this image
13
Which is
NOT
an advantage of taking photographs rather than drawing observations by hand?
Photographs are more accurate and to scale.
Photographs are better evidence and can convince more people
Taking photographs is quicker and easier
It requires less equipment to take a photo
14
