The Solar System Quiz

Question 1

How are electromagnetic regions other than visible light used by modern telescopes?

Answer 1

For discovery of objects not detectable by visible light (e.g X rays from remains of an exploded star)

different (electromagnetic)
waves can give different
types of information (1)

in discovery of objects not detectable by visible light
(1)

Question 2

Why are some telescopes located outside the earth?

Answer 2

Telescope placed above the atmosphere, where waves are not absorbed/reflected/ refracted by the atmosphere

(e.g like with light that might be shifted into
infrared region by red-shift (1)
• (some) infrared is
(strongly) absorbed by
atmosphere (1))

Question 3

How has telescope development impacted our understanding of the universe?

Answer 3

improved magnification allowed clearer, more accurate observations of galaxies

Improved range of wavelengths detected which allowed more and varied data to be collected (e.g discovery of
objects that don’t emit visible light )

discovery of objects not
detectable by visible light
(1)
• more information / data
can be collected (1)
• different (electromagnetic)
waves can give different
types of information (1)
• produce magnified images
(1) 
(space telescopes) produce
clearer images / images
unaffected by Earth’s
atmosphere (1)
